Here are some of the problems we are facing for Membership 2 plugin on http://checkthisout.net.au/ after upgrade:
1) When some one is registering it is not showing in list of users under membeship2 users.
2) Also we added 2 additional fields using Cimy User Extra Fields but it is not showing on Registration form,
3) How can we add captcha on registration form?
Looking forward to hear from you.
