Since remove and install previous users can't log in

[loopee]

Hi

I'm new here, so please be patient with me.


Following issues with the installation of Roundcube 1.03 on Mavericks Server 3.2.2
Previous users are unable to log into roundcube via browser but newly created users can log in fine.

Clearly I've screwed up with the database and I'm hoping there's a way of either removing all of Roundcube (yet again) and reinstalling hoping that the Postgres DB will be recreated for all users

or

locating the database with the new users and making entries for the previous/older users?

Your help would be much appreciated as I'm totally green to this
