Upgrading from free version 3.4 of Membership to Membership Premium 3.5 causes the plugin to break / white screen.
I understand there is a potential conflict between Membership and Contact Form 7 and Captscha, so I removed those plugins. Still Membership doesn't work properly. So, I removed every other plugin I had but the Membership plugin still doesn't work. I also changed themes and this doesn't make the plugin work. I also tried regenerating permalinks. Arrrgh! Looks like I may need to downgrade to a full version of Membership but older than the current one, yes?
When I say it doesn't work properly, I mean... the subscription signup box that is added to the registration page whitescreens the page. When plugin is deactivated, the page shows up again. I also tried switching to a different page for signup. Same problem.
Any suggestions would be very much appreciated. Thank you!
