I am currently running Plesk 10.3 on CentOS 6.
After installing suPHP and doing the chmod +X command on my folders, I still receive 500 Internal Server Error messages when running even a simple php info script.
After checking (what I think is the correct error log), I saw that it said that the necessary files found in var/www/html were not there.
Is var/www/html supposed to be empty? because there is nothing inside that folder.
