Reply To: Desired Plugins Causing Problems.

It sounds like the memory allocated to PHP is being exhausted. This can happen if the hosts default value is too low and a resource “heavy” theme is being used.

Here’s a link to an excellent blog post which explains how to increase the memory allocation:

The method that will work for you depends on the web host. I suggest starting at the top and working your way down.

I hope this helps, let me know.
