I set up the following shortcode a few months back and it worked just fine.
[mb_user_profile_register id="user-profiles" label_submit="Register" role="vendor" redirect="https://www.ergafrica.com/supplier-agreement/" password_strength="medium" email_as_username="true" ]
I have updated meta box a few times since then, and this week the redirect no longer works. I tested the redirect link and its working just fine, but when i do a test registration it wont redirect instead i get this message
