 * Hello,
 * I’ve been using the pre2. version of your plugin for years with no problem, today
   I updated to 2.5.1. Set up everything, it seemed to be ok (frontend looking as
   it should, list of older submissions updated), but when actually testing the 
   function, the SUBMIT button is not working.
    When submitting without email address,
   the error message is triggered, but when with proper email address, absolutely
   nothing happens, no success message, the pop up stays there, and no new submission
   is added to the waitlist. This is the WC error log:
 * 2021-11-18T15:00:38+00:00 CRITICAL Uncaught Error: Call to undefined method WP_Error::

 * I’m still on WP 4.9.8. WC 3-8-0. I tried to unable a few other plugins to test
   if they are in conflict, but nothing is working.
    I would be very grateful if
   you could help me with solving this. Thank you very much in advance.
