Site Down After Upgrade

[Wirral.Talk]

Hi everyone, last night i upgraded to version 5 and to my amazement everything went fine with no problems and at the end it shown a button to go to admin control panel so i clicked on it and it went to a blank page.

I then tried to go to my main page wirraltalk.co.uk and again nothing but this time there was a server error message http 500.

I have contacted vbulletin and its coming up to 24 hours now with only one reply asking for my ftp details but since then i have heard nothing. I have requested help on the main forum and again nothing apart from a message from team member Trever asking what the error log was showing.

My host has also taken a look and cannot find a problem.
Can anyone please help me at all?

And what is in the error_log? It's a server error, so something should be in there.

Also, this is an upgrade from what version? And did you upload the required. htaccess file? And have you tried reloading all your files (perhaps they didn't all get uploaded correctly). And did you modify both config.php files?

Hi Lynne, thank you for your reply.
Lots of the errors are showing as this type of thing...

[07-Mar-2013 07:11:20 America/Chicago] PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 4096 bytes) in /home/wirralta/public_html/core/vb/datastore.php on line 156

I upgraded from the last version 4.2 (i think it is) i uploaded the htaccess file that came with version 5 i have to admit i haven't uploaded all the files again yet. And yes i changed the two config.php files.

Its really crazy because the upgrade went perfect with no errors ect until it had completed.

If you try to go to your site, and then immediately check your error_logs and see something like this:
[07-Mar-2013 07:11:20 America/Chicago] PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 4096 bytes) in /home/wirralta/public_html/core/vb/datastore.php on line 156

then you've got a server issue that needs to be resolved. You will need to show that error to your host in order for them to fix the issue.

My host did see the error above and said...

If you check the error_log file in the same directory, you will see that there is some memory issue:
[06-Mar-2013 22:27:45 America/Chicago] PHP Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 4096 bytes) in /home/wirralta/public_html/core/vb/datastore.php on line 156

Normally the limit is 128mb, we have increased to 256mb and finally 512mb but yours still crash. It could be a compatibility issue with the version of vbulletin and php

Hi Amaury, version 5.3.20 it says on my hosting control panel.

That shouldn't be the problem, then.

vBulletin is currently only incompatible with PHP 5.4.x.

In your core config.php file, did you select to use any of the caching options?

No just changed the database and username and password didn't get to involved in the rest really. :s

Just really don't know what to do because the vbulletin staff member who is dealing with this seems lost and only replied twice in the last 24 hours and both times is about logging into ftp not to do with the actual problem.

Does anyone else have any tips please? It would be very much appreciated...
