Can you go to the forum admin > Options > Global Settings. Over on the right there is an option to ‘Enable combining and caching of forum CSS files’. Is this turned on? And if so can you turn it off and update – then reload a forum page although clearing the browser cache is never a bad thing.

And let me know…

this option is turned off.

so thats not the problem.

Curious if this worked before then – there have been no changes to the mechanisms involved. So… next.

What Simple:Press theme are you using and does it require updating (see the WordPress Dashboard Update page)?

yeah everything it up to date.

i use Default 1.2.12

Can you try switching your Simple:Press theme to the ‘css-only’ theme option. If that works OK then it suggests that something may have changed in your web server to disallow the use of php files to create run-time CSS files which is what ‘default’ does.

If the changes does NOT sort it then I must start tp suspect some sort of corruption on one of the new updated files…

yeah not working.

should i try restore a backup.

and what folder do i need to restore

Could you give me a link to your forum page just in case I can see anything that might be a cause?

Hey Simon,

Are you running any caching plugins? I notice you are getting a fatal error in your console which looks to be killing everything. I don’t have any experience with WordFence but I see the file wfBrowscapCache.php which is why I mentioned caching.

<b>Fatal error</b>:  Allowed memory size of 134217728 bytes exhausted (tried to allocate 1115 bytes) in <b>/var/www/web537/problem-with-post-edit-buttontml/rank/wp-content/plugins/wordfence/lib/wfBrowscapCache.php</b> on line <b>50203</b><br />

If you are using caching you will need to exclude the forum from this completely as SP is dynamically displayed. 

Also, the error is actually stating that your PHP memory of 128mb is exhausted, you might want to try increasing your PHP memory limit especially if you are running lot's of plugins or a few heavy use ones. I'm not sure if this can be related to caching. 

Also, I have removed the login info you posted above. Although this is essentially a private support forum, it’s still not a good idea to post login details with passwords openly.

Please PM these details to myself, Mr Papa and Yellow Swordfish (or see admin list in stats section) with a link to your forum, login details and a link to this thread, in case we don’t resolve it, another admin can take a look later.

i deactivated wordfence, nothing changed

there is no cache plugin installed.

OK, the only other thing I noticed is a jquery conflict. Wasn’t sure it was as promising as the fatal error (which I’m now not seeing by the way).

However, on further investigation I can see that it appears something is loading it’s own jquery library from googleapis, which is not recommended due to it being quite different from the WP jquery library. This could potentially be coming from your WP theme, so the first thing to try would be one of the default WP themes such as twenty thirteen to see if that resolves things.

Might not fix things, but it’s always best to eliminate the obvious problems before looking further!

Yes – as Ike says there are a lot of jQuery libs being loaded by theme or plugins that are non-WP standard. I see also that you are actually getting 2 copies of the forum displaying and I assume that never used to happen.

So I am going to have to ask the obvious question… have you also changed your WordPress theme?

changed to twenty 13 but still broken.

i changed theme back.
