Actually i have changed the max_file_upload in php.ini from 40M to 600M. The Wordpress admin page is working fine but the site displays 500 error. I tried reverting the changes made in php.ini, still issue exists. Tried executing the command: free -mh
total used free shared buff/cache available
Mem: 990M 542M 96M 51M 351M 233M
Swap: 634M 6.3M 628M
This is the first time I am starting the server, so I have installed all the plugins at the same time using ALL-in-one migration. If it is a problem with the plugins, What should I do? How do I find which plugin is causing the issue?
