Login problems after clean setup

edit

I've installed Askbot 0.7.48 from the RPM package provided in Centos 6. After a few fixes I had it running but with one problem. I can't login in any way from the main login form, even after deactivating all the social logins and leaving the local login alone.

When I submit the form, two different errors appear, the first one is related with the database, the message is:

DatabaseError at /account/signin/ no existe la relación «django_authopenid_userassociation» LINE 1: ...penid_userassociation"."last_used_timestamp" FROM "django_au...

(Translation: The relationship django_auth... doesn't exist). I leave here a screenshot: http://i.imgur.com/n9eUnog.png

The second error is this:

----------------------------------------
Exception happened during processing of request from ('192.168.122.1', 48937)
Traceback (most recent call last):
  File "/usr/lib64/python2.6/SocketServer.py", line 560, in process_request_thread

  File "/usr/lib64/python2.6/socket.py", line 450, in readline
    data = self._sock.recv(self._rbufsize)

----------------------------------------

I can login perfectly from the admin dashboard login though.

My setup is this:

• Centos 6 standard (core and EPEL repositories alone)
• PostgreSQL 8.4.13
• python-psycopg2 2.0.14
• Askbot 0.7.48

How can I solve this problem?
