Have you tried:
– deactivating all plugins to see if this resolves the problem? If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-related problems?
– resetting the plugins folder by FTP or phpMyAdmin? Sometimes, an apparently inactive plugin can still cause problems.
Thanks esmi, I’ll look into it and report back the results.
I had the same problem. It appears to be Simple:Press Forum 4.1.2 causing my problem with viewing the widgets screen when activated. When I deactivate the widgets screen is normal.
I am a newby. Installed 2.8.6. and have the same problem. No plugins activated.
No help, no screen options, no widgets, Ad new post are white letters on a white backround, can’t switch between visual and html….
Anyone?
@djmasterm: Try re-uploading the wp-admin and wp-includes folders.
Esmi, I did…but still the same problem
Did you use a fresh download of WP?
Yes I did. I use Firefox 3.5.5. on a apple could that have to do with this problem?
Highly unlikely. The usual culprits are:
– corrupt wp-admin and.or wp-include files
– bad plugin(s)
– bad theme
I don’t use any plugins yet.
theme: ThreatToCreativity 2.3
Have you tried switching to the default theme to see if that resolves the problem?
I switched back to the default theme but still nothing works
Keep the default theme active and try re-running the upgrade via Admin/Tools/Upgrade.
I get an error:

Unpacking the update.
