Title: Forum Entry Bug
Post by: AabeckControls on May 06, 2019, 05:08:05 PM
I have been accessing this forum with the following bookmark:
http://advancedhmi.com/forum/index.php#c1

However lately, on more than one computer and with IE and Firefox, when I click on Support Questions I get a blank screen, not a 404 screen, that says the page can not be found. If I click on the latest thread reply I do go that thread, then can go back to all the categories in the forum. This also happens whether I am connected directly to the internet via WiFi or through the office firewall on the wired network.
Title: Not Acceptable! Error
Post by: bachphi on May 06, 2019, 06:27:04 PM
For me, I keep getting this error:

Not Acceptable!
An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security.

It's happened on more than one laptop with Chrome browser.

It's not just you. When this happens I either change https to http or use incognito mode, I use chrome, but it happens on every browser.

Thanks for the tip.

It should work properly if the bookmark is edited and corrected to go to: http://advancedhmi.com/forum/

Just like the attached picture shows.

I think you are missing the big picture.  It's a known issue, Archie has known about it for weeks.  It doesn't always happen.  For me, it happens when I click on "View the most recent posts on the forum."  The big picture is not how to make it work, what about the new person that is interested in AHMI.  I would be turned off if the website isn't functional.  I highly recommend thinking about it from that angle.

FYI, my bookmark was changed to http://advancedhmi.com/forum, still did not work reliably.
Now changed to https , will see what happens.

Maybe try this (what my forum bookmark is currently set to): https://www.advancedhmi.com/forum/index.php

Some might consider using one of these as well:

   Main site: https://advancedhmi.com/
   Documentation: https://advancedhmi.com/documentation/index.php?title=Main_Page

There has been an ongoing issue with the forum and it seems to be related to the hosting provider. I have very little luck getting a resolution because the hosting provider wants me to show them the problem. Since it is intermittent to those who do see it and I have only ever seen it once, it makes it impossible to show them.

Did you switch the host provider recently?
I think the problem started after the new year and the mobile friendly update.

It's been the same host provider for quite a few years. I thought maybe it was related to the changes to the forum, but the one time I saw the problem, it was on another forum under a different domain and not using the same package, but on the same hosting provider.

How exactly do they want you to demonstrate the problem?  Screenshots?  I can recreate it every time at home.  If I can provide the necessary information to them, I will.
Title: Re: Forum Entry Bug

In Chrome, I can recreate it by just following the link from the 1st post, by AabeckControls, and clicking on Support Questions (or any other category).

This seems to be true only if I'm not logged in to the forum or if I log out, clear browsing data and access the forum page again.

The last time I talked to tech support, he said he needed to find in their logs. I am guessing the log is rather extensive, so he was looking for a fairly close time of it happening. Since it only happened once for me and would not happen again, I was unable to get him what he needed. It would take someone to repeatedly generate the error and provide the public IP address of their router.

I edited my previous post so try following those steps in Chrome.

It was recreated several times in the past 15 minutes.

I tried this in Chrome and I do not get the error. I then tried in FireFox and it DOES give me the error, so I am going to call tech support with this information. Thanks for the steps to replicate.

Here is one more piece of information:

The link from the 1st post actually connects to the page as Not Secure and seems to maintain that even if I add "www." at the beginning or remove "#c1" at the end, and press Enter button.

See the attached picture.

They just made an adjustment and I can no longer repeat the error. Does anyone else still see it?
Title: Re: Forum Entry Bug
Post by: Godra on May 08, 2019, 04:12:22 PM
It seems to be working now but the "Not Secure" part seems to still exist (even if the address is typed as: "http://advancedhmi.com/forum/").

I'm not sure why the browser is not changing it once it sees it is a secure site, but it should change it to
https://www.advancedhmi.com/forum/

Microsoft Edge showed the same, so it seems to be the way server responds.

I get the same thing, so I guess the first entry into the forum lets you go in unsecured but clicking any link then changes to secured.

Not sure if that bug could be exploited by some malicious people to hack your website.

I'm sure its a possibility. It looks like this problem has been around for a while:

It doesn't do the same with this address:

http://advancedhmi.com/documentation/index.php?title=Main_Page

It switches correctly to https.

But it did the same on your main site, with this address:

http://advancedhmi.com/index.php?main_page=index&cPath=1

Maybe a simple solution might be to make sure that all http requests are converted to https by the server.

This regardless of whether it's www.advancedhmi.com or advancedhmi.com.
Title: Re: Forum Entry Bug
Post by: bachphi on May 09, 2019, 07:38:14 AM
Agreed. All bank, financial sites do that automatically, convert http to https.
To Phrog James's point, a new or casual user will not have a bookmark,  so it's would be a frustration for those users.

FYI, things are better for me with bookmark of https://advancedhmi.com/forum/
