Allowed memory size of xxxxxx bytes exhausted (tried to allocate xxx bytes)

The following message (the numbers may change slightly!):

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 74 bytes) in /folder/path/to/file

means that your php script is trying to use to much ram to parse. This can generally be fixed by reducing the complexity of the page / script you are trying to run (eg try removing plug-ins from Wordpress, removing components from Joomla, etc.).

If you are unable to reduce the memory usage of the script you should upgrade your account.
