Lately I am wondering why my visual editor is missing and all I can see is only code editor. The problem might occured when I played around with my database but I am not sure if that was the problem. After searching around the forums, I have found the answer on the visual editor problem.

All you need to do is go to the left side panel and click on Users then click your profile, untick Visual Editor then click save then tick again Visual then click save. Try to create a post then you can see your visual editor again. Hope this helps! Ciao!
