I check the error log on my server, and i found this:
[Sun Nov 08 03:59:01.499688 2015] [core:error] [pid 12193] [client 122.53.125.2:29475] AH00124: 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.,
Probably it’s related to server error.
