Re: Lots of server errors... what's going on?

I meant backend cache issues in nginx or whatever they are using, not browser front end caching.

Re: Lots of server errors... what's going on?

Understood. I Admin a vBulletin driven forum. In fact, I QBed the first vB4.xx Beta release in a real world environment for very large forums and found most of its scaling problems and coding problems that made it perform differently (read worse) in the wild than it did in the test box. The user end fixes of clear cookies and cache to get updated style cookies didn't work was what I was trying to communicate to the techies.

Re: Lots of server errors... what's going on?

Clearing the browser cache can some times fix this.

Chrome has been knows to have some issues with vBulletin.

Re: Lots of server errors... what's going on?

This is not a browser issue. Browsers are not built around a spec for vBulletin. Browsers are designed around HTML, CSS, and JS standards.

With respect to the current issue. I just looked at my browser console for errors.

I get a 500 error accessing "Why Cal?" thread from the main Portal

Failed to load resource: the server responded with a status of 500 (Internal Server Error)

Code:
http://www.cruisersforum.com/forums/f47/why-cal-63946-2.html#post1015404
I get the same error when accessing w/o the #:

Code:
http://www.cruisersforum.com/forums/f47/why-cal-63946-2.html
Clearly, there must be something wrong on the routing or caching of pages on the server, or something deeper.

I just tried it in Chrome and Firefox, and it worked the way it was expected. Can you try with a different browser and report back?

Just curious. Have you changed the number of posts per page from the forum default in your User CP?

Other issues aside, the "most users online" number reflects "within the last 90 days" so it does change.

I have been fine in explorer 9.0.9, but I have noticed pages taking a bit of extra time loading. And now that I think of it I have gotten some white pages, where nothing loads in the frame...

Re: Lots of server errors... what's going on?

FWIW,

1. I tried using Windows Explorer and it seemed to work ok (once) on a thread that I could not access in Chrome, but I don't want to do that regularly.

2. The problem is getting worse over time.

3. I have indeed changed to 40 posts/page.

Cheers,

Jim

No changes from forum default. Now, the forum I manage also uses vB, but version 4. When we experienced this issue using 3.8, it was because we had wonky load balance servers and corrupted datatables and filepaths.

There is an issue with that, though I did think it was sorted. You might try changing back to 10 (default or explicitly 10) and saving the option. View a thread you have had trouble with, then change back to 40.

I hate 10 posts per page...

Re: Lots of server errors... what's going on?

white pages are 500 errors. You are not seeing the http response because your browser is not displaying it, but its there.

Error seemed to go away for the last day for me, but returned recently today.

try using "curl <URL>" in terminal and see what you get back.

EDIT

Unfortunately, using curl as is doesnt take session information therefore should return something like it did for me. Perhaps its user session => server related?

just tried

Code:
http://www.cruisersforum.com/forums/-cal-63946-2.html
again, and still get 500 error

try performing this logged in

Re: Lots of server errors... what's going on?

I get this sort of problem from time to time. I'm guessing that it's due to vBulletin requiring a rapid response or it spits the dummy.

Tried Internet Explorer and Chrome but did not notice any difference.

The primary cause looks to have been Windows deciding that now's a good time to down load some massive upgrade. Being Windows it doesn't tell me about this. Some other programs are almost as bad.

I've also changed to Avast which seems to run a little faster and doesn't seem to have as many upgrades.

Whenever it all gets a bit slow I usually have a couple of cleaners installed. CCleaner and Wise Care are the current favorites. Running these gets rid of quite a bit of junk. I also use Control Panel/Uninstaller to get rid of any programs that I don't really need.

Recently while mucking round with Avast I found a "Scan on Bootup" function and ran it. It took forever to finish, the % count is way off and it claimed to find a few viruses.

All seems to be going well now...
