Out of the blue error...(Classifieds)

[Pipe Hitter]

I have had this installed for over 6 months and now this error shows itself. Any ideas or suggestions?

Warning: file_exists() [function.file-exists]: open_basedir restriction in effect. File(/path/to/php/headtags.htm) is not within the allowed path(s): (/home/regirom4:/usr/lib/php:/usr/local/lib/php:/tmp) in /home/regirom4/public_html/classifieds/pp-inc.php on line 528

Just go to Admin => Global Options and clear the bogus path under header footer or headtags whichever ones your not using
