Error when I try to add CSS

[hungry4knowhow]

Hey all I also got this error while editing image urls to show the full url of my site so they could be detected by vbacmps.

I added the above code to my root .htaccess and created an htaccess in /forums directory with the same code but still recieve the same error when saving the style.

I do have Suhosin installed on my server.

Thanks for any help you might be able to give,
Steve
