Not Acceptable! An appropriate representation of the requested resource could not be found on this server. This error was generated by Mod_Security [SOLVED]

Working on programming for so many years, it amazes me that i have really much to learn. This recent issue cropped up out of nowhere.

I decided to disable mod security , which is a bad idea honestly. But true enough, i found the culprit. It seems when you pass a get parameter with special characters, our websites seem to be on high alert against hack attack

<IfModule mod_security.c>
  SecFilterEngine Off
  SecFilterScanPOST Off
</IfModule>

What i was passing is the name of a client through get command. Yeah i know . It came out as link.php?name=M&M

I changed then parameter to a session id i had given before and it solved the issue. sigh. another lesson learned.
