roll back to version before 3.5.1

You can always download a prior version and upload it via FTP. However, the better solution is to figure out why you are having those issues, since there are many of us running 3.5.1 without these problems.

As a start, try disabling your plugins to see if the problem goes away.

In wordpress my site looks like my pages are published but when I go to the specific link it says “nothing is found.”

It was working well before I update to the 3.5.1 version.
The theme is Twenty Eleven.

I would love to go back to what I had before because now I have nothing up at all.

Please help.
