Added fields should be ready for input

Additional comments

In Profile edit form the custom fields work as expected.

Make sure the "Guest" Usergroup is allowed for the "Edit Custom Field Value" action. Please check the permissions tab of either the field or field group.

Sorry, I tried but that doesn't change the behavior. Also, if it would work, it would be inconsistent as others fields wouldn't require that permission setting.

Actually, you have a special case here because the registration form can be filled out by visitors not logged in, similar to the contact form. So you need to make sure "Guest" can edit the value. I think by default ACL only allows Super Users to set it. That's how our ACL works, deny everything until it's explicitely allowed.

I need to check why exactly it doesn't seem to work there then.

I got it. I have to set the permissions in the field. But why isn't it working with default permissions set? Doesn't mean default "default"?

Also, why are some fields working without the permissions set right? This seems to be an UI issue. As I can't find the correct way to get this thing done, I wonder how many users will face the same issues.

[Bakual]

There is another issue open that "color" and "editor" fields can't be set to disabled. So those always allow to be edited. That may be what you saw.

It should work also with field groups and global permissions. Sounds like a bug sneaked in with the inheritance of those settings. Thanks for that finding, that helps. I know where to look now. Just have to find the time for it :)

Please test #13676
