I have only lifetime subscriptions on my site, and I stupidly started messing around with renewal groups and now some users are signing up for products and getting a "future" dates for the tart date of the product (Dec 31, 2037) instead of the present date. If I have 10 products that I'm selling with lifetime subscriptions, what should the renewal groups be set at? Sorry, but I don't quite get it. Thanks!
Each product should have a unique renewal group so they do not overlap and create "future" dates like you are seeing. You can read more about it here: http://manual.amember.com/Product_Renewal_Group_Explained Note: Once you have fixed this, you will need to adjust any existing members manually.
