 * Hi, I am a longtime Form Manager Plugin user and it was working fine. I just 
   got a notification that there was an update available so tried to update, but
   it would not Activate. I got the following message:
 * Plugin could not be activated because it triggered a fatal error.
    Fatal error:
   Call to undefined method fm_db_class::DatabaseCheck() in /home/postpr7/public_html/
   aquariumcarebasics.com/wp-content/plugins/wordpress-form-manager/wordpress-form-
   manager.php on line 138
 * I deleted the plugin, and re-downloaded and installed it. When I tried to activate
   it, I got the same message again.
 * Thoughts?
 * Thanks!
