My original email was not very clear.
On my backup server I want to remove the 2.0RC2 installation and get a 
1.7.x installation running.
However I removed all the RB2.0RC2 files and then dropped the reviewboard 
table from mysql database.
I then did a clean installation of 1.7.25.
I then imported the data from my old server (which was running 1.7.18) - at 
this point I would have thought I would have a 'clean' installation.
However the rb-site upgrade fails and when I visit the homepage I get the 
errors below.

It is almost as if there are some settings files that are stored someone 
not in my installation directory and not in the mysql database.
Might there be some files related to django evolutions that I have to 
delete?

Dan
