After installing 3.5, the content menu bar (when adding or changing messages) is not displayed.
I tried the following five 'solutions':
1: I installed 3.5 and then deactivated the active plugins one by one
2: Using FTP, I changed the name of the plugin folder and than installed 3.5 in admin.
3: I have dowloaded 3.5 and than uploaded with FTP everything except the content directory.
4: I removed all inactive plugins
5: I've changed my theme in a WP theme.
Between every 'solution' I have put my backup back.
Nothing worked until now. Is there someone who can help me?
