I am currently unable to edit portions of my theme within Wordpress any more. When I click on Customize or try using the Visual Composer plugin, the page freezes up or I get a HTTP 500 error. When I contacted my theme support, they said I have exceeded my default php memory limit and give me this error message:
Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 687373 bytes)
That said, I upgraded my PHP memory limit to 128MB back in November when I had a similar issue logging into Wordpress and editing my site.
Is there a problem with my php memory limit not working like it should?
