Thanks for the response. I followed your advice but now am getting the following error:
Fatal error: Cannot redeclare WA_AuthenticateUser() (previously declared in /home/content/53/8580253/html/webassist/security_assist/helper_php.php:28) in /home/content/53/8580253/html/WA_SecurityAssist/Helper_PHP.php on line 46
Maybe because I'm also using SecurityAssist? I can't get to the admin panel now...
I can edit using the cms from within Dreamweaver, though.
