[TYPO3-english] felogin reports: CE type "login" has no rendering definition

[Stefan Kaufmann]

Hi List,

I am runing TYO3 6.1 and the to-be-released responsive introduction 
package.

The felogin plugin outputs the error:
ERROR: Content Element type "login" has no rendering definition!
in the frontend.

Tried so many things but no luck.
It must be a misconfiguration problem, but what could be misconfigured. 
I am running out of ideas.

Best regards,
Stefan
