I upgraded wordpress from 3.6 to 3.9.1, and all of the posts on the first page are behind each other, so noone can read them. The first 10 is like that, but the latest posts are displaying fine and are readable.
Everything was fine before I upgraded. How can I downgrade back to 3.6? Or can you solve my problem, please?
I'm not a programmer, so please, write everything down :)
