We looked into this in a connect meeting. We added:
to the top of the page to show PHP errors and saw the following error:
Warning: session_start() [function.session-start]: open(/var/php_sessions/sess_b8e1188f2b2fdb856f7c22525d0a5ab0, O_RDWR) failed: No such file or directory (2) in /hermes/web05b/b962/pow.josecpais/htdocs/ContactForm_GMC/WA_ValidationToolkit/WAVT_ValidatedForm_PHP.php on line 3
This error indicates that the host has a problem with the session.save-path setting in the php.ini file. I recommended contacting the host to have them fix it.
