Horde Webmail Setup on Server (Troubleshooting)

Hi, I'm looking for someone that is experienced in setting up Horde Webmail (an open source mail client) on a shared server. The shared server have already an installation of horde and it appears that it support it. The only problem is that once the horde installation instructions are followed (via shell access) and try to login for the first time - only the login screen appears (while in reality, it is meant to login as administrator the first time - to create login details etc) I need someone that can help sort out this particular issue. Thank You Jo
