What kind of error message do you get ? Also, does it create different login and register page ? If so can you please send me your url ? I will check and let you know.
The default error of WP Armour: Spamming or your Javascript is disabled !!
No different login or register page, it is an Elementor form but on the backend and not on the frontend.
Please provide e-mail where I can send login credentials to, I will setup a test environment for you.
