I reopened this topic, as it was the most relevant to me right now: https://premium.wpmudev.org/forums/topic/membership-plugin-is-not-working-with-several-themes ...But the topic may be good and dead. So here goes:
I'm using Membership with Business Feature for my video tutorial site. Initially, everything worked fairly well. Now, however, I can't edit any of the access level rules because the drag and drop won't work. I have a free Test Drive membership for 7 days, finite. Then the user should be able to upgrade to any paid membership or be downgraded to Stranger level. Renewal limit is 1 day.
I figured out that I have to manually activate users, bummer, but I can do that for now. However, users are not being presented with upgrade options on the Account Info page. The signup page doesn't offer ANY of the subscription options, it only signs people up for the Test Drive account. They should be able to pay if they wish, for a full account.
