For one of our client I was investigating the issue where the website when accessed shows a Not Found error. On looking at the server error logs, I found logs as below.
Request exceeded the limit of 10 internal redirects due to probable configuration error. Use 'LimitInternalRecursion' to increase the limit if necessary. Use 'LogLevel debug' to get a backtrace.
Further checking, found that the issue was with the .htaccess file which conflicts with the one in the root directory of the account. Renaming the unwanted file OR correcting the redirect rules solved the problem.
