I have been running links now for over 3 months. I've never had a problem like this. This is the error message:
Content-type: text/plain Error including libraries: Missing $ on loop variable at /home/www/ufoseek/admin/site_html.pl line 423. Make sure they exist, permissions are set properly, and paths are set correctly.

I checked that line in site_html.pl and there is no loop variable on it without a $. I didn't change anything since the last time I built the pages. I don't understand why I get this error. Any suggestions?
