Login Type E-Mail: Unique checkbox not working

[suntrop]

I have updated to PW 3.0.184 last weekend. Noticed this week, Mail-Login is not working any more. I guess there must be changes made in core or the Login module (had something ~3.0.164 before).

The Login module says now, "To use email login, you must enable the “unique” setting for your email field." When I enable the checkbox "Unique" and save the "email" field, the checkbox is cleared again.

There is no error message. But it is probably because there are already 30 email addresses more than once used.

Problem now: It would be quite hard to check which accounts are the latest/active ones and which could be renamed or whatever. 

Anybody with an idea? Anyone knows when things changed in the Login module?

I don't use this module but maybe you could perform a direct search in the databse via phpMyAdmin.

Yeah, I did this. That's why I know there are 30 addresses that are not unique ?
