I am running s2Member (free version) on a WP Standalone site.
I am migrating to a multisite network installation and I want to upgrade to s2Member PRO.
How do I do that?
In the Network Admin page of my multisite, I click the “s2Member® Pro (Upgrade)” link in the upper-right-corner of the screen but nothing happens…the s2 Multisite Config page remains blank.
Also, I am running the current standalone site as www.example.com and the multisite that I am migrating to as dev.example.com. Once I complete the migration, I plan to switch dev.example.com to www.example.com. Does that complicate my paid-for upgrade to PRO?
Please help me with the steps to (a) upgrade to PRO and (b) complete the migration from dev. to www.
