I've been attempting to get Omeka working with 1and1.com hosting. I've had reasonable success and the system is installed. But...
When I try reach the 'admin' page I am bounced to the login page. After I enter my credentials I just get bounced back to the login page without any error messages.
After looking through the code and tinkering a little bit I see that in controllers/UserController.php there is a check for $_POST variables. I added some debugging messages and discovered there are never any POST variables passed into the login function.
Perhaps there's something getting in the way with 1and1 Hosting?
Or is there something else causing the trouble?
