Hello,
I'm trying to solve a very strange problem regarding MediaWiki on Apache:
Every time I edit a page and typing /etc/ or <html> I am receiving the message:


The website is unable to display the web page
501 - Method not implemented

And when I search a word like "package" I am getting:


Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator, webmaster@optier.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.

More information about this error may be available in the server error log.



I disabled the mod_security on the server by SecRuleEngine Off, didn’t work.
I restarted the server after every change.

Also, for some reason I can't see any log activity in Apache when I get these errors as if the HTTP request had never reached it (I know for a fact that the logging is working well).
System:
MediaWiki 1.14 running on
Apache ver httpd-2.2.3-22.el5.centos.2
With mod_security-2.5.9-1.jason.1

This is part of my httpd.conf file (minus all the descriptions and disabled stuff):
