Ok so I was able to get a error log file, this is what it contained:
[Mon Apr 04 21:58:32 2011] [error] [client XXX.XX.XXX.XXX] 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.
I'm not sure where to put any of those commands...
