In my Personal site when i enter the Domain URL i was getting a message Forbidden You don't have permission to access / on this server When i contacted Hosting company they said We have checked and found that your domain permission was reset so we have reconfigured your permission so please check and update us. now my domain is working Fine But How did all of sudden my Domain Permission Changed Any FTP hack some one made ??????????????????????????????????????????
Probably some cPanel glitch that occurred when they updated it, which changed some htaccess permissions on your site, I don't think it's related to hacking.
Check the error logs in cPanel>Error Logs This usually provides a clue as to what's wrong. Perhaps wrong permissions or ownership of public_html or .htaccess
