[TYPO3-english] CSRF error on login

[alexis nicolas]

Hi there,

I've installed v7.2 choosing postgreSQL. Everything worked fine, except when I try to log in the backend I get a nice "The CSRF protection token for the requested module is missing or invalid" error message. I looked for information over the forge and other sites, tried to apply a patch, checked DB config in localconf.php, ran install tool from typo3/install as xavier perseguers suggests, but nothing worked...

Has anyone get information or - better - a solution to fix that?
Thanks by advance.

Regards,
Alexis
