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 Twenty Eleven theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading the wp-admin and wp-includes folders from a fresh download of WordPress.

Thanks esmi,
I already did step 1 and 2 above before posting. Strangely overnight things are working again, I guess the issue was with the server and that the hosting company made som maintenance during night.
Have a great day!
