So basically, we're having a reoccurring problem that "usually" happens when we refresh the forum's current page by way of our browser buttons. Sometimes people get it randomly, but that's how I can get it to break at will, sort of speaking. What happens is that drop down menus (such as the one for the user cp) get frozen open, post functions in the reply boxes disappear, the "multi quote" button disappears all together, code breaks when replying to someone as if rich text wasn't supported, many of the moderator functions don't work or take forever to process (such as deleting posts, and the selecting things via checking the boxes), the reputation buttons don't work at all, and the skin selection require you to click an "ok" button after clicking a new name instead of the new skin loading right away.

This problem goes away when someone clears their browser's cache & goes to a new or existing page by not using their browser's refresh button, so I wouldn't be surprised if it had to do with some sort of "auto clean" function that's been disabled or deleted. I'm not an expert by any stretch of the word, but those are the things I've noticed, and I'm using IPB 3.1.4


Also (this may or may not be related), we get the following error (the 5th screenshot) when we try to give reputation after clearing the cache & temporarily eliminating the problems above. This really isn't a big deal, but I think it has do with the fact that when we enabled the comments field, we did so without doing something else that needs to go with it. These errors happen on all of our skins, but I figured that taking my screenshots from the IPB default would be the best.

... so yeah, if anyone's run into similar problems and or has any ideas on how I can go about figuring this out, you'll have an entire forum thanking you. Also, I'm sorry if I posted this topic in the wrong place. This just seemed like the place where forum related questions went.

Oh boy. That won't be easy, as it's intermittent problem.
From what I've seen problems like that are usually caused by some hook(s).
Did you find out, if there is any specific browser involved, or it doesn't matter?

I'd try couple of things.
First, I'd open a ticket. They may find something.
At the same time, I'd try to investigate by yourself.
Disable one hook at a time and run the board for couple of days.
See, if you have any complains.
If the problem still there, re-enable that hook, disable another one....and so on.

Yeah, I didn't really expect anyone to have an instant fix for me, but I figured something like this would at least be annoying enough for anyone who's dealt with it before to well, have done something about it.

Also from what I've gathered, it happens on multiple browsers & multiple skins (I mostly use Netscape & Blackbird but others use Safari, Opera & Chrome), so I don't think it's a browser specific problem, which may or may not be a good sign. I'll definitely look into all of the hooks, as I'm pretty sure they're at least tied into the reputation issue, which came about at around the same time.

Either way, thank for replying so fast, and I'll keep this thread updated with what we've tried.


Edit - I know this wouldn't really be a "fix", but do you know if there's something I can do to make the forum not save any temporary files to begin with? I mean in theory anyway, people would only have to clear their cache once, and then the problem shouldn't return because what they'd need to clean wouldn't return in the first place.

I'll be around :)

While I won't claim to understand what all of this means, I figured it couldn't hurt to relay what our hoster managed to do to fix this problem in case others came across the same issues.

It was a setting in the PHP backend that was causing cached pages to randomly fail (that's why it would work when you did a force-refresh or if you cleared your cache). For this side it was a PHP setting that conflicted with FastCGI on IIS in php.ini

cgi.rfc2616_headers = 1 (old setting)
cgi.rfc2616_headers = 0 (corrected settng)
