Fatal error: Maximum execution time of 30 seconds exceeded in /store/jails//...ow_core/database.php on line 305

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 24 bytes) in /home/joeservs/public_html/test/ow_core/database.php on line 341

and I get that error sometimes on my live site but it usually points toward newsfeed and not just database

you may need to increase the memory capacity of the BD in PHP.ini something like this:

, Maximum size of POST data will accept That PHP.

; http://php.net/post-max-size

post_max_size = 8M

You see it in phpmyadmin when you give to see the ability to import you have to file if you need to increase it is insufficient in php.ini that amount

But in my case it's happens when I try to put a avatar in my group or when a new member signup using Facebook, as I related on this topic: http://www.oxwall.org/forum/topic/6325
