Hi

I build a website using Joomla 4
When I register, I get this error:
Model UsersModelRegistration not supported. File not found.
User Registration Model could not be loaded.

I checked function getUserRegistrationModel in helpers.php but it tries to load the model from JPATH_SITE.DS.'components'.DS.'com_users'.DS.'models'.DS.'registration.php'; but in Joomla4 it's not there

we use version 4.0.2 but according http://www.joomlathat.com/updates/atupdate.xml the latest version is 4.0.1

also we can't register on joomlathat.com, because recaptcha doesn't work. It's a common issue on Joomla 3 sites which use mootools. Need to have a small patch in mootools-core or need to disable mootools if it doesn't really need: https://extensions.joomla.org/extension/mootools-enabler-disabler/
