When visitors fill in the registration form and click the "register" button, the form refreshes without registering. No validity check is done on the fields.
This problem has been occurring at least since Apr 18 (when the last user registered successfully), and the only thing I can point at is that I updated all my plugins, including UM. I didn't change UM settings.
I disabled unnecessary plugins but it didn't help.
I don't have this problem from my PC (it works as usual) but all those who try to register do. I had one of them share their screen on Skype and indeed it's not working to them.
Here is the registration form. You can try with dummy data.
