[TYPO3-english] FE login error after update to 4.3

[Stephan Viftrup]

Hi
It seems that updating to 4.3 has broken my felogin somehow. It worked 
fine before and now a normal login simply refreshes the page, shows the 
message from "styles.content.loginform.goodMess" but does not log in the 
user.

No fe_session is created in the database.

I have performed the compare database several times after understanding 
that it might influence it, but without luck.

Any ideas
Sincerely
Stephan
