When I click check link I get this message:

Warning: preg_match() [function.preg-match]: Unknown modifier '/' in /home/content/w/e/e/weezee/html/xxxxxx_admin/links.php on line 625


I am running Zen Cart v1.3.8a. I reuploading all the links manager files, before that, the line was 623

I think I posted this in the wrong forum. help with logo sideboxes sorry.
