I'm just preparing to upgrade to version 4 - on Monday, hopefully. I'm working with a test installation in a different directory while Amember 3 continues running my site. So I can test out a lot of things, but I'm reluctant to set up the Aweber API integration while the Amember URL is 'wrong', in case this causes trouble later. So that leaves me with questions for anyone who's using Amember 4 with Aweber: 1. Do 'newsletters' work OK? I find as soon as I activate - but don’t configure - the Aweber plugin, the newsletter page in Amember admin is replaced by an error message. I'm hoping this will just go away when the plugin is configured. What's your experience? 2. How does the newsletter block work? I see you get a list of newsletters with checkboxes on the member page, and checking/unchecking instantly subscribes/unsubscribes you to the list in Amember or in Autoresponseplus 3 (which I've already integrated). Does this - the subscribe/unsubscribe - work the same for Aweber? (Assuming the lists are set to single opt-in, of course.) 3. Do you know if I can set up the Aweber integration now and move Amember to a new directory later? - or would that upset Aweber and cause everything to fall apart? (Of course if I could safely do this, I could find the answers to #s 1 and 2 myself.) Thanks!
