Security Rule error when logging in

[Silentfaith]

This is happening every once in a while to myself and my friends who are working on the site, when we go to log in we get this error which I will list below. If we click the back page button and try to re login the error goes away. I'm not sure where this file is and what I need to do.

The page you are trying to access is restricted due to a security rule.

If you believe the security rule is affecting the normal operation of your website,
you can disable it by adding the following lines to your .htaccess file:

<IfModule mod_security.c>
# Turn the filtering engine On or Off
SecFilterEngine Off
</IfModule>

mod_security is getting upset over something, your host might send you the log file which will give you a specific reason as to why.

The above .htaccess rule should resolve the problem, but it will reduce the servers security for your site.

I just spoke with my host, they had me put in a support ticket looks like they will attempt to resolve it.
