I am trying to get the Create Joomla User plugin to work with Acymailing 7. I have toggled it on, kept the rest of the settings at default. I then go to import and paste in an email address. I choose a list to subscribe to, press ok and the user is imported, and added to the list, but no Joomla user account is created. Have I missed a step? I have Joomla users allowed within the Joomla congfig. My Joomla is 3.10.
