XF 1.2 Forum front page now shows error

[Solari]

Greetings.

This is a bit of an urgent problem. Our XF forums are now showing an error on the front page of the forums, simply saying "The requested page could not be found."

This is at http://www.gatorcountry.com/swampgas

I'm trying to troubleshoot this - the category pages themselves seem fine as well as thread indexes inside each forum itself, but the forum front page is showing this error.

Thanks for any suggestions,
Ray

The DNS has propagated on our end but the error is still happening, unfortunately. Also, it apparently doesn't matter what setting we set in the Options, as long as we submit *anything*, the front page comes back so it's not just Basic Board Info.

Have we run into some weird bug that's taking down our forum front page every couple hours? Maybe some cron task failing out?

The cron tasks shouldn't be touching the option settings.

Which add-ons do you have installed?
Try disabling them all by adding this to library/config.php

$config['enableListeners'] = false;

Then monitor and see if it still occurs.

 

[Solari]

Thank you, trying this now and will let you know. What does that line do?

Ray

 

[Paul B]

It disables all add-ons.

 

[Solari]

Okay, we're still having this issue. Any other suggestions?

I can only assume it's some sort of cache issue.

It's not something I've ever heard of before.

 

[Solari]

What can we do at this point? It is seriously impacting our business. I also contacted our host and they said nothing has changed on our server either.

Thanks,
Ray

It looks like you are using nginx 1.4.4? Is that the latest version for your OS release? If not you may want to think about upgrading (on Debian using DotDeb nginx is at 1.6.0). Also, check your rewrites in your nginx vhost configuration for the forum setup. Make sure that (if you changed from the location of the actual forum structure location) that you reflected any changes in the vhost also.
Are you using any caching (memcached, opcache, etc)? If so, when you made the change did you restart both the http server and the php processor (I assume php-fpm)?

Here's what our server folk say:

"nginx 1.6.0 is in the updates so we can upgrade it at any time. You don't use memcache as far as I know, and eAccelerator is the only cache I can see enabled in PHP. You also only use nginx as a proxy cache, not as your main web server, that's still httpd, so there are no rules there. Your rewrites will be in the .htaccess in your forum root."

Have them look at your proxy setup then... it may be something there. Apparently you are using Apache 2 on the back end so check and make sure the .htaccess in the forum root is correct also.
I have no experience with eAccelerator (I use Zend Opcache and memcached myself). I honestly don't think it's something related to the forum script but more likely http/cache configuration.
