Paypal Pro Forms tab not appearing

Hi there

I’ve got S2Member Pro installed, and the tab for Paypal Pro Forms does not appear under settings. I had it working before, but something has since gone amiss. Therefore the shortcode I had working on a particular page (https://mygsis.gsis.edu.hk/aboutus/people/alumni/) seems to now be inert, not being rendered.

I’m not sure what changed exactly, except that, I have, since the last time that I checked this was working, upgraded Wordpress and S2Member. It is in one isolated part of the site that does not receive a tonne of traffic, so this has gone un-noticed until now.

Any advice would be appreciated…

Oh, and I have also disabled all plugins besides S2Member to eliminate plugin conflicts, to no avail.

Ugh. I knew I had overlooked something. I found that it was disabled under Other Gateways. I enabled it and wahlah. Fixed.
