The fix that I found that worked on every borked WordPress site on which I tried, is just replace the core WordPress files with fresh WP 3.5 core files. It didn’t work at first, but I just had to clear my browser’s cache and cookies and it worked! Simple.

It is simple. Delete your wp-admin and wp-includes directories as well as all the files in the root directory. Basically your deleting everything EXCEPT the WP-CONTENT directory. Also before you delete everything, you will need to get the database name, username and password out of the wp-config.php file, because you will need to put that information back into the new file, or else you will get a database connection error.
It is actually easier than it sounds.

When I had this issue, all I had to do was delete the old WP core files and then upload brand new ones. It did not work at first, I had to clear my browser’s cache and cookies, then hard refresh, but then it started working.

I figured out the solution. All I need to do was delete the old WP core files and upload brand new ones. At first it did not appear to fix the issue, then I cleared cache and cookies and did a hard refresh and it started working. I hope this helps.

I took the advise of WPyogi, and this issues is not listed, and none of the generic fixes worked (I did try every one of them).
