I had incresed to the 1024Mb and time to 600 but no use , the error happening at the cache and load.php

What effected my theme to cause this error. Do commentlines cause the errors

I am using Mamp, do i should work on real server when size increased

1024 MB is not enough is what I understand from the error message. Try increasing it more
