I I have manually updated wordpress to 3.5.1 (after backing up everything with wp-db-backup) and downloading to computer.
However the dashboard is not working - I cant go from visual to text, the upside down triangle buttons for screen options dont work and in the side column (eg publish box)
When I go to the page the code comes up instantaneously then disappears.
The site displays ok but i cant edit it.
I have deactivated plugins for no result.
I have tested the default theme - same problem.
I am running out of ideas.
