WPEM used to be responsive with chat tech support, but now that you have to submit a “ticket” it can take a long time (days) for them to respond to fix an issue. They need to fix the 3.3.3 plug-in issue as soon as possible and advise everyone!
WordPress helped to rollback (restore) the website before the WPEM plug-in update (3.3.3) from yesterday. Sent WPEM tech support a ticket to fix their plug-in.
