I am unable to use visual editor after upgrading my WordPress software. It started with 3.7.1 and continues after I updated to 3.8 (this evening).
I can edit in text mode but not visual mode. I have dumped cache and tried 2 computers with 4 different browsers. My user profile has not disabled visual editor. I have disabled all plugins and set to default WP theme at http://www.kiwanisofarlington.org. I still cannot edit in visual mode after any of these changes.
