After logging in, IMAP capabilities displayed - no Inbox

I recently got Roundcube installed and it appears to be running, however it does not display the users mail or Inbox or anything. When I log in, it only shows me the capabilities of my IMAP server:

• CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT

LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE AUTH=PLAIN cp01 OK Capability completed. Tried PLAIN: Resource id #25

It seems as if Roundcube is asking for the capabilities of my IMAP server, but then not using them to actually open the users mail.... Any help would be appreciated.
