Hi, 

I had the same problem after updating from 0.3

With this version (0.5.1+)

The login check is case sensitive, and the user when had its first login  write some shift letters, it save in the db.

Check the records of this user in the user and identities tables.

Best regards. Gelo

Hello,

I recently upgraded to 0.5.2 and something happened with one new user that is preventing him from logging in. Logs as follows:

Any suggestions? Thanks!
