Button insert link on front wp_editor not working

I found it at last!

Using the browser debugger, I found that there was a “editor.wp” which was undefined (in the complete version of the js file).
Then I understood that the “wordpress” plugin was not used in the editor.

When calling the function wp_editor, I was setting a list of plugin : paste, wplink, textcolor.
It was working until a specific WordPress update.

I just had to add the “wordpress” plugin in the list, and now it’s working.
