Many plugins and themes add JavaScript and CSS files to your site. While this alone isn’t necessarily a bad thing, using several plugins that do this can bog down your site with loads of requests for these files.

How to Resolve Fatal Error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes)
Posted by admin on May 28, 2010 - (0)
Recently, when either adding new plugins or upgrading plugins in Wordpress, I encountered this error message:
Fatal Error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 30720 bytes)…
This means that Wordpress needs more memory to run a process than the default PHP setting (usually 12M, in some, 32M). For a non-techie guy like me, the error is frustrating, and very alarming.
Before you panic, there are actually simple solutions to this problem that even a non-techie person can do. The first solution is the “standard” or proper way to resolve it, however, it depends whether you have access to the file that needs to be updated. The second one is much easier, a “hack” to a specific Wordpress file, however, you may need to do it again everytime you perform a Wordpress upgrade.
