Hi,
Just some information in relation a problem with the WP Security Scan Plugin.
When this plugin is activated the options menu on the right hand side of the page does not work properly. The field menus appear expanded and will not collapse, this means that you cannot access the save or update form button underneath.
One simple solution is to deactivate the WP Security Scan Plugin when creating or editing forms and activating it when finished with the form.
Having the WP Security Scan Plugin activated does not seem to affect the appearance, operation or data entered into the form.
Its just a minor thing to keep switching the WP Security Scan plugin on and off.
Hope this is useuful!
