Very odd one. I was creating a post when I typed in the title field I hit the tab key and then all of a sudden the visual editor stopped working. I changed nothing, no plugins, zero. I can use the HTML editor but visual editor allows not inputs on the body field. What is strange is I can log into my admin account on another computer and visual editor works fine so this rules out any issues with plugins, bad files, etc. I have tried resetting safari, deleting cache, etc and still no luck. Any idea?
