I have updated Ubuntu to 14.04 and apache stops working.
I have reinstalled apache and all dependencies with no success.
When I enter localhost I see apache indexing the www/ folder but it is empty (although I have several files and folders). When I type in a folder I know it exists, I get a 404.
This is the error.log output:
