I have a domain on bigrock and the hosting of the domain is on VPS using the CWP panel. Now I create a subdomain that's HTML pages are working fine but the .php files are not working and showing the error message
"Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later."
The domain is on CWP and it is working fine only the subdomain is showing this issue.
Don't get why this is not working fine.
