Visual Editor Not Working After Updating To WordPress 3.9

WordPress dropped its 3.9 version Wednesday, and since then I have read tons of threads on support forum with people having trouble in all new TinyMCE 4.0 editor, a.k.a Visual Editor.

I had the same problem with Tricks Panda after upgrading to WordPress 3.9, but I took me just a few seconds to solve this problem.

If you’re facing some issues with TinyMCE 4.0 or visual editor is not working after updating to WordPress 3.9, then here’s how you can solve this problem.

In most cases, having users go through this process solved the problem:

Tons of changes took place with TinyMCE in 3.9, which crashed a lot of plugins. Those crashed plugins can cause a lot of problems, so it’s better to deactivate all the plugins. If you have installed plugins for shortcode buttons or things like that, you should immediately deactivate all the plugins. Go back to your post editor to see if it’s working or not.

If it’s still not working then don’t activate them immediately, but wait some one. Now, let’s change your WordPress theme to default Twenty Fourteen theme to check it your theme is causing this error. My editor caused due to my WordPress theme’s built-in editor buttons. At this point, your editor should probably work.

If it’s working after changing the theme, then you can activate all the plugins one-by-one to check if they’re not causing any problems either.

If it’s still not working, then you should manually empty browser cache. It all these solutions are not working, then there could be a JavaScript issue. Follow these instructions from WordPress codex to diagnose JavaScript errors in your browser. Then, visit WordPress support forum and open a new support thread with a detailed report of your problem.

Don’t forget to leave a comment with your WordPress 3.9 experience.
