Today I have noticed a lonely error (for the last week) inside of my error log file:
[datetime] [core:error] [pid 11220] [client 187.33.2.88:34964] AH00135: Invalid method in request "GET /cgi-bin/php HTTP/1.0
I am on apache 2.4.10 and php 5.5.17. Is there any reason to be worried about it? What might have caused it?
