Thank you for the advice. We did all of the above previous. I guess we have to do a more in depth scan. I am just wondering if the attack changed some settings, that makes the site breakdown.
Site is not listed as infected with malware. Was hoping that specific error notifications like this one, would help to identify the issue: ?AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use ‘LimitInternalRecursion’ to increase the limit if necessary.
