We use the latest version 2.0.17 with “Ultimate Member – Google reCAPTCHA” and latest WordPress version 4.9.6.
Apparently there was an error at the custom validation, I had to change this code $ultimatemember->form->add_error to this $ultimatemember->classes[‘form’]->add_error
I also updated all other plugins and now it works as it should.
Thank you anyway!
