[support] d6 conversion problem

[Marty Landman]

I've upgraded a d5 site to d6 and now nothing's working. When I go to 
the user page to log on it says '4' where the content should go, and 
after going back to online mode via phpmyadmin queries all I get are 
page not found errors. Cleared the caches from phpmyadmin.

The server error log shows nothing and the website error_log shows 
this a bunch of times:

[28-Nov-2010 12:33:53] PHP Warning:  Unknown column 
'language' in 'where clause'
query: SELECT src FROM drupal_url_alias WHERE dst = 
'category/image-galleries/news' AND language 
IN('en', '') ORDER BY language DESC, pid DESC in 
/home/catskill/d6/includes/database.mysql.inc on line 128

I ran update.php to update the databases after removing a bunch of 
unused modules /before upgrading, and the site was working well. I 
guess because of that the d6 db has 123 tables while the live site's 
db which I copied to make the d6 site has 132 - didn't notice that before.

Any help appreciated, at a loss as to how to proceed. I upgraded all 
the modules and the themes before my site went to never never land. 
Now I'm stuck big time.
