Hi, thanks for your reply.
Yes, we had to deactivate the plugin because it was generating an error when we created a new user, it seems that it was an error when sending the email of the new registered user (we use POST SMTP plugin with Google API)
Please tell me if you need me to activate the plugin again for how long because as it is generating an error when registering we prefer to deactivate it until the problem is solved.
Thanks!
