A common error with software like WordPress, Magento, and OpenCart etc is the php "Allowed memory size error." Increasing the memory limit is an easy solution. This memory_limit can be changed in the php.ini in thepublic_html folder in your hosting account. This error can creep up in your website during the normal development process. The following is an example of the error:

Fatal error: Allowed memory size of 436894354 bytes exhausted 
(tried to allocate 45785643 ) in Unknown on line xxx

This is because of a php variable data being stored in the memory that is not cleared while the php scripts are running. This can happen with misconfigured software or an over writing of the core php.ini  file with another server software application installed. Increasing memory size is not the solution in many cases, and the usual root cause is an issue with configuration of the application rather than the memory limits. Usually there is a memory leak (not unless the website has VERY large data set!
