I'm getting an error saying there is an "illegal division by zero in line 571" from my edit_post.cgi file after installing the Anchor hack. In other words, line 571 is code from the hack that replaces the original script. I've since replaced the hack code with the original, effectively disabling the anchor hack after editing posts. Could someone look at the code and tell me what might be wrong with it? Here is the code from the hack...
Thanks in advance!
