 * I’m getting this error when I try to use the plugin:
 * **Fatal error: Call to undefined method stdClass::add_help_tab() in /home/content/
   q/u/e/questweb777/html/wp-content/plugins/visual-form-builder/visual-form-builder.
   php on line 317**
 * I am using the current version of wp. I just installed this to use on a site.
   Any suggestions on how to fix this?
 * Thanks!

 * Sounds like your install doesn’t include all of the files in the wp-admin folder.
   I’d download a fresh copy of WordPress and upload the wp-admin folder directly.
