I went in today to make my first blog post after the upgrade and the visual editor is missing.
I have taken the following steps to resolve and it has not worked:
1. deactivated all plug-ins. I am only using get the image and wppa
2. ensured the your profile box is not checked so visual editor should show
3. re-uploading the wp-admin and wp-includes folders
4. changing to 2010 theme
5.cleared cache after
Please advise on fix for this ASAP
