Restore database problem, pt. 2

I was merging with older entries to my new WP and then made a backup. On the other WP, it was a version 1.5 while my current and active WP is 1.5.1.1. I followed the Restoring database from backup and fixing Siteurl procedures exactly. The query was successful. Then I upgraded to 1.5.1.2. Now, my WP is not showing up on main page, it’s total blank and the Dashboard page is also empty. I’m not sure what went wrong? The siteurl is correct and I was able to view and edit entries as well as use the rest of WP admin sections without a problem. The main page and dashboard are the only things that’re not showing entries. I’m stumped by this. I’d be grateful for your assistance. Help! TIA.
