I just updated my WP from 2.1.3 to 2.2 and I saw an error in my dashboard, see it: Screenshot
Where last activity must go it show my index page, what I did wrong? I changed the theme and it happens the same.
What can I do? I tryed to delete all files and put the new ones of version 2.2 but it didnt solve it.
Sorry for my english i'm spanish.
EDIT: I found the solution, thx anyway. Here
