Can someone tell me if what are the best methods for debugging why a 500 error was thrown for my website. I have OpenCart installed and suddenly stopped working. Now there is 500 internal server error and i can not access both admin and frontent. I have checked htaccess files and they are OK.
Also, along with all of the various opencart folders like admin or website root, there is created core dump files They all start out core. with numbers attached like core.1024 with about 42MB file size.
I have contacted my Hosting provider and they said that the problem is with OpenCart code but I can not find any solution for this. Help please?
