I just 'backed out' of a installation attempt of Admin Profiles. Everything was working fine prior to this. Now I am getting this error message when I try and go into my cart - it seems unrelated to the admin problems I was having. Can anyone help?

Warning: main(DIR_WS_TEMPLATEStemplate_default/common/html_header.php) [function.main]: failed to open stream: No such file or directory in /home/kazbonco/public_html/bridgeroasters/cart/index.php on line 43

Thanks,
