This is still a hard one for me.
I get the editor, but still having some issues with the visual/html buttons. They don’t show up like they schould be.
I’m getting js errors too when pressing them. And the height off the textarea changes to 0 so I cannot see it after pressing the visual/html buttons.
I tried all methodes posted above, and others I found on google, but none is working as it schould be.
Hope someone could help me with this.
