[TYPO3-english] Frontend User Management (datamints_feuser): Auto login error?

[Morten Kjems]

Typo3 6.2.6
Frontend User Management 0.10.0

I am trying to get auto login to work after registration.

In typoscript I set:
plugin.tx_datamintsfeuser_pi1.register.autologin = 1

That has no effect. So I also check auto login option in the flexform.

See here: http://i.imgur.com/Vc6LPcr.png

None of the two above settings have any effect. 

The user is created but is not logged in.

Any suggestions?
