I've not seen a single error like this in several months, and I've only received a very few reports from others. This suggests that the errors are being triggered by something subtle, and probably not on the server.
I've found that any of the following can stop the errors happening again:
Re-start my  browser removing cookies and clearing cache.
Re-starting my computer or smartphone.
Keeping my software up to date
Switching off my wifi router and leaving it off for 10 minutes before switching it back on.

As a now-retired systems software developer, I find this error really frustrating and think we should be able to get to the bottom of it if we analyse the evidence carefully.

It happened again to me this afternoon and I spotted something odd on the error report screen I had not noticed before - see my screen capture attachment. Underneath the You can use this key to fix the problem yourself... line, there was a digit 2 which was a link and when I hovered the mouse pointer over the 2, the destination appeared on the bottom line as expected. What was very odd was that the destination www .seattlehumane.org/name-of-some-php-file (obfuscated here) seemed to have nothing to do with melodeon.net. I did not follow the link! I decided at this point to capture the screen contents. (If you look at Gromit's original message in this thread, you will see that he too appears to have something odd between the You can use this key... and the If you are unable to fix the problem yourself... lines.

Can this be reported/investigated please Clive/Theo.

I then decided to see what was displayed if I clicked on reload (which meant retrying the attempted login2 action). More surprises - reloads repeated the Error 403 page but the repeats did not include the weird link until after about 3 or 4 reloads, I logged in successfully!

The OS/browser combination was Windows 7 Pro 64 bit with Firefox 50. I am prepared to invest more time on investigating this problem if the forum admins or the SimplePortal developers need anyone to carry out further experiments.

Got this error again tonight when trying to post to Lester's 250K page view thread. I just clicked the Reload current page button until the error page was replaced by the updated forum page. I needed to click it four times I think before the error page was gone. On one of the reloads, the digit-2-link to the seattlehumane web site which I reported earlier appeared on the error page. Very strange.

And again tonight on my Nexus 7 Android tablet running Chrome which suggests the problem is independent of hardware, OS and browser. Touching the browser Reload button four times (IIRC) again got me through the error pages to the melnet page I was attempting to load. One of the error pages included the digit 2 link, again to the same non-existent seattlehumane page.

Vince, I think I'm right in saying the you are the only person reporting this particular error message. Makes me think it might be something local to you such as your wifi router or your ISP.  I did find that sometimes clearing caches and a router re-boot would help.
Title: Re: Error 403
Post by: vof on December 06, 2016, 01:02:15 PM
Theo (and Clive?)

Not sure how useful it is to continue this discussion in this melnet forum - I would rather follow it up offline and via a discussion with those technically responsible for the Simple Machines software and the specific melnet site - but I will give a hopefully short response below.

I am certainly the only person actively pursuing this at the moment but you can see from earlier posts in this thread that many other reliable and technically able members have been hit by the problem. They accept it as an unavoidable evil and don't always report it whereas I don't accept it as a necessary evil. My background in software development tells me I may have this tiger by the tail and I'm reluctant to let go having got this far.

FWIW, my experience suggests this is not a problem local to individual computers but is rooted in the forum software or the melnet incarnation of it. You suggest that cookie and cache clearing is the way to go to overcome the problem. After doing that, the problem may appear to have gone but that does not necessarily indicate that the cause has anything to do with the browser cache or cookie state. My experimental evidence that just clicking reload/retry enough times at the point of error gets you past the problem suggests to me that the error state is very transient and doing almost anything may overcome the problem.

This is what I would like to happen:

1. The advice on what to do when Error 403 is received is updated to suggest trying up to half a dozen reload page actions. I am interested to discover whether that action works for other people as well as myself. (BTW, are the words of advice on the Error 403 page customised by yourselves or a standard part of SimplePortal?)

2. A bug report/conversation be started between the likes of myself and those who understand the design of the system and how it has been installed and configured. I have already offered to help diagnose the cause of this problem but without access to someone who has the knowledge to respond to specific questions on how the software is designed to operate, we will not get very far. This thread on melnet is fine for initial reports of the problem but it is not the place for detailed technical questions and discussion. My view is that this problem is not caused by finger trouble or lack of familiarity with the user interface but lies much deeper and so needs input from others who know more about the software and melnet's use of it.

"lies much deeper and so needs input from others who know more about the software and melnet's use of it."

I'm as thick with computers as I am with music but, if that was the case, surely it would affect all users? Or, at least, all users on he same browser?

I don't have the expertise to discuss the details techicalities behid this. Clive is the IT professional, but he may or may not have the time to follow it up.

In the past I have been able to send details of individual instances to our web hosts. In all these cases the error message was different and the cause was badly set up security on the server which was triggered by certain key words.  As far as I know this error has not recurred recently.  I've not seen it myself and I've not received reports from others. There have been several changes to the server hardware and software in that time which may be relevant.

Vince if you would like me to forward details to our web hosts I am happy to do that. The information I need to give them is: a screenshot of the error message the date and time of the error, and your IP address would be helpful. Please send that by email.

Post by: vof on December 06, 2016, 03:55:00 PM
Rees, Lester

I would be very interested to know whether my recommended approach works for you - when the Error 403 page appears, click your browser Reload/Refresh button - usually the button with one or two circular arrows - four or more times giving the melnet site time to refresh the page after each click - after which you eventually reach your expected melnet page.

I would also be interested to know whether any of your sequences of Error 403 pages include a link part way down the page with the link text simply the digit 2 and the link target a page on the seattlehumane site. (Hover over the 2 link to show the target, usually at the bottom LH corner of the browser screen.)

Vince, I think I'm right in saying the you are the only person reporting this particular error message.

I rarely look at Melnet with either of my Android devices (Google/Nexus tablet, HTC phone) but when I did, this error (or something extremely similar) was quite common.
Title: Re: Error 403
Post by: Theo on December 13, 2016, 04:50:05 PM
Following on from receiving some details from Vince I think I have identified where the error message is coming from and I have made an adjustment to a setting that might help.

If you have been getting this error please let me know if there is any improvement or not.

Rees - from my experimentation, I suspect you don't need to click on Back, just try repost/reload - the button with circular arrow(s) on it - a few times.  Vince

I'm referring to the button - usually with a circular arrow or two semi-circular arrows - on your web browser (Firefox/Chrome/Safari/IE) address bar (that horizontal bar at the top of the window that contains the forum.melodeon.net/index..... web page address). Mobile devices may look a little different.

I'm suggesting that just clicking that button a few (4?) times when the Error 403 page is being displayed allowing each click to be actioned before clicking again will eventually get you through the Error 403 pages and onto your destination melnet page.

Lester and Rees have suggested similar but more complicated sequences of actions but I think mine is simplest, provided it works (:) and I would like to hear feedback about how effective it is for other members.

Yes, I've noticed it happening again occasionally since the change of hosting company and I agree the F5/refresh ploy does not always work (but I suspect that is because it depends on what you were trying to do at the time the Bad Behaviour module shows you the red card...)

Safari bypassed this, and presently I'm on my tablet. Will try desktop FF again later in the day

But the issue seems to be "dirty cookies"

"Edward, oh that life in software development and bug diagnosis was that simple  (:)   Vince"

Although I'm sure that no offence was intended in the above, I've stayed out of this discussion/investigation since I was warned off. (Not offended in any way shape or form, mind! Computing and computers are a completey alien world to me.)

However, after spending a lifetime having to find and cure faults which sometimes eluded the best specialists that vehicle manufacturers main agents cold produce, I'm still at a loss here as to why this faut is being blamed on the origin of the site when it seems to only occur with certain users?

I'm sure that Theo/Clive or whoever, could quite quickly estimate the percentage of users who are experiencing this difficulty, and I'd lay odds that it's a rather small proportion. So why should the signal (or whatever means by which the site is being is transmitted and enables us to view it and contribute) only change from being "good" to being "bad" for some of the members? Is it really possible for the "origin" to transmit, whatever it is that it transmits, of different qualities to particular receptors, unbidden?

Is it not possible that sight of the wood is being missed because of the trees? Especially as (I believe) the site is now coming via a completely different server (whatever that is?). I'm fully aware that I may have just put one of my size 10's in my gob again, but never mind, my skin's as thick as the rest of me!!! 

I haven't experienced this problem in 29 days of being connected.

I got it yesterday on two different computers for the first time in a month or so.

I get disconnected on iPad, iMac and (as today) on this PC, attached via a completely different server.   I'm beginning to wonder if the 'bug' might be something to do with accessing melnet on several machines?

I've recently been loooking at the technicalities of peristent login sessions ( i.e. being able to re-open your browser and find you are still logged in to a site like melnet) and it is certainly possible to allow multiple independent sessions, i.e. to be able to do the same concurrently from different browsers, devices and IP addresses. I don't know exactly how this is done by the Simple Machines Forum software that melnet runs on, but it works for me: I don't have any trouble using FF and chrome from at least 4 different devices regularly. I used to have trouble sometimes with an Android tablet, but I don't use it often enough to know how well that works now.

Yes, I connect variously from 2 pcs, an iPad and an iPhone, without normally needing to log in again.

I just read posts in Chrome and if I want to post something I use Opera, which I keep on my machine for annoyances like this.  Works like a charm, for some reason.

I'd lay money that when user sessions get confused like this, it's because your ISP is caching webpages badly. Not easy to do anything about that, other than getting a decent ISP.

Error 403 happening again, after I get presented with a login dialogue having clicked on Show unread posts since last visit. My F5/Reload trick appears not to work at the login dialogue.

Theo: did my whitelisting - if it was still in place on the Krystal host - get recreated after the recent move to the new host?

The whitelisting is a forum setting not a server setting so it should still be in place.
Back home now and I have checked and your IP whitelisting is still in place.

The error message on the server logs gives the reason as "POST more than two days after GET"   which from my not very detailed technical knowledge suggests that it could be a caching problem along the lines that Clive suggested a couple of posts back.
