I hate upgrading. I have never ever had an upgrade without there being a problem.
I upgraded from 2.2 to 2.3.3. Now, I've got Array showing up on the front page. When I click on it it says "comments closed". On another blog, it goes blank. It's showing 3 times in the plug-in section. 7 times in another blog
When I click "Users" in Admin, I get: Fatal error: Unsupported operand types in /home/cecon46/public_html/what-smells-so-good/wp-admin/users.php on line 55 on all the blogs
In case you ask, yes, I let Worpress Update database.
