I use WP via Netfirms and was trying to upgrade from 1.5 to 2.0.x. Unfortunately, I failed to do that but was able to restore my back-up.
Couple of problems now:
The categories don't appear anymore. Instead, the code is visible on my site (e.g., WordPress database error: [Unknown column 'category_count' in 'field list']
SELECT cat_ID, cat_name, category_nicename, category_description, category_parent, category_count FROM wp_categories WHERE cat_ID > 0 ORDER BY cat_name asc)
Also, I cannot get into my admin pages any longer. I get this error message:
Warning: main(/mnt/w0510/d21/s41/U0000c5K/www/italofile.com/nfblog/cp/wp-includes/cache.php): failed to open stream: No such file or directory in /mnt/w0510/d21/s41/U0000c5K/www/italofile.com/nfblog/cp/wp-settings.php on line 108

Help me! I just sent out some work-related lit that points to my site. You can see it here:
