My SP forum simply stopped working suddenly. Initially it reported out of memory error so I had server support up the PHP allocation to 1024M. Now it hangs for a minute and the browser returns error 324 eventually. It also hangs the wp-admin dashboard when the SP plugin is activated but not individual programs:

For example, /wp-admin/ hangs but others work OK, like:

/wp-admin/widgets.php

/wp-admin/admin.php?page=simple-press/admin/panel-forums/spa-forums.php

 

Things I have tried include

Repair DB

Delete the plugin, download current ver and re-install

Delete all other plugins

It’s a VPS running CentOS. My error-log file shows nothing related.

The only thing that changed in the environment as far as I know was a security patch update a week ago that required a reboot.

Of course I update plugins as soon as my WP dashboard advises of an update. But with all plugins physically deleted from /wp-content/plugins/ it still hangs. 

But I have not updated a theme. However, I will reinstall the current default SP theme that I use, as a precaution.

It's not browser related. Users use a variety of browsers.

I am a newbie, but try this one: Disable all cache !!!!

I have just disabled object cache on my host and performances have suddenly started to get better. It seems to me that SP is allergic to cache systems...

allergic?  it wont be a simple press thing... it would be a wp thing...  if you were running an object cache, you would need to optimize the rules for wp (depends on which object cache you use)...

a caching plugin for wp is a whole other story...  they simply try to cache the wp page which is wrong since its dynamic in nature...  so if you have wp super cache or w3 total cache, you can use them, just have to tell them not to cache the wp page the forum is on...  not doing so wont slow things down, just give wrong information...

@capitano let us know what you find...

Well, first things first I guess. Regarding the security patch on Wed that occurred a few hours before the forum issue arose:

"Nothing was changed on your VPS. Changes were made to the main server node."

I will now test things like the SP theme and SP plugins - strip it down and see if it works.

I am not a Linux/PHP coder so my debugging ability is limited.

I am seeing a syntax error when you try to run the forum page but it is in something to do with 'slides'? Does that mean anything to you? Not sure if it has any relevance however - it is the only thing showing up in the script console.

Thanks - no, does not ring a bell.

Now I am at the end of things I am competent to try. Happy to pay for an investigation. I can PM credentials for SSH, FTP etc. as required. Is this something I should request in the Paid Work section of the forum?

lets try a couple more things first...

I see you are running wp super cache...  are you caching the forum page?  can you try clearing your cache and perhaps even disabling wp super cache (making sure the advanced-cache.php file in wp-content is removed too)...

lol, is your wp theme really called simple press?  since you theme may have been updated, can you try a quick temp change to the default wp theme?  thinks it flexslider plugin is causing the js error Andy alluded too though doubt it would bring down the forum...

what is odd is that I dont see a single http request coming from the site when you try to load the page... so basically, no wp code is loading yet... and no wp code means no sp code...  something going south real early...

lol Mr P - yes, The WP theme is called SimplePress, by Elegant Themes - not to be confused with any forum elements.

I will test your ideas tomorrow early.  I had deleted Super Cache (no, it does not cache /forum/ ) but I was not aware of advanced-cache.php

Thanks
