[Plugin: Web Security Tools] Broke my site, damn it!

I’m sorry about that, but I didn’t see your comment until today.

There are two behaviors of this script which protect your site. First of all if it detects any alteration to certain PHP code it will shut down your site. If you are getting “service unavailable” errors than chances are either your site is infected, or you have changed code that you shouldn’t have.

The second behavior of the script is that it will blindly patch security holes by changing file permissions of directories and files. This will break any non-secure scripts you have on your site.

If you didn’t alter the security plugin than chances are you have a plugin running which is a security risk, and since it can no longer write to files on your server it has broken your site. Example: timthumb
