Creating a new topic because I mistakenly replied to a resolved topic.
When a user signs up through Paid Memberships Pro the Validity is set to “1970-01-01 0:00:00″ and member cannot add a post. I have already set the Expiration for the membership level but it still does the same thing. Only when I manually set to “unlimited” does it allow the user to post. It's extremely important that it is automated without manual intervention.
