Keep getting 'User not registered' after installing ocs and trying to log in

Hi,

I have recently installed OCS Inventory and have been able to access the console once. I don't really know why I can't access it anymore.

When I try to log-in with username: admin and password: admin after installing the database i keep getting : "User not registered".

I have tried to find solutions on the web but I can't seem to find any that work for me!

Any ideas?

Kind regards,

Jan
