Hi,
I tried several UserPro updates and none of them solved the problem… Disabling theme’s, plugins etc. etc. Nothing worked. Going back to 1.88 did the trick over and over again.
But last week when I started using WordPress 4.0 (and UserPro 2.1), the problem suddenly disppeared. No idea why or how.
Installed the UP2.2.-update this morning. Everything’s still ok :).
Problem solved. 🙂
Thanks for the answers @Support and @CentralGeek.
If I understand this correctly, in my case – whereas an e-mailaddress is required – using Twitter is far from ideal.
I’ll just disable it 🙁 (at least for the moment), and have a good think about the things you wrote @CentralGeek.
Thank you, this is very helpful.
