Warning: preg_match(): Unknown modifier 'f' in /home/azure/public_html/includes/classes/template_func.php on line 30

This is the error I'm receiving. I just reinstalled Zen this afternoon (to fix the HTML Area problem I've been having and it's now finally resolved) but I'm baffled. It's working fine on the English side but I'm getting this error on the French side.

This is the link to the main page which is working just fine.... then click on the French flad and you will see this error.

Thank you!
