tinymce langs error: Failed to load plugin url: /wp-includes/js/tinymce/langs/fr

Hi,

– Clear the Browser Cache
Upon our search, we found users suggesting that clearing the browser cache worked for them. The first thing you should try to do is clear the browser cache or use another browser. This could very well be an issue with your computer.

If this does not fix your issue, maybe the issue is with your install?

– Replacing TinyMCE Scripts
Maybe this issue happened after you updated? Well, it’s not likely, but maybe something went wrong in the update process. Try replacing /wp-includes/js/tinymce/ folder with a fresh copy.
