Allowed memory size exhausted problem

The problem is that you don’t have enough memory allocated for your php script in your php.ini file. there are two ways to solve it

  1. increase the memory allocation which might require you to increase the actual physical memory you use
  2. give up on some features of your site.

There is no one root cause for such a problem which you can debug and “solve”, the problem is a result of the actual usage of the accumulative features of your site and it is not caused by a single one of them (although probably one of them is more memory hungry then others)
