I think what might be happening is it's trying to load Visual Editor, which has been broken since how long ago who knows. To fix this, go into the top right and find your icon. Click it and go to "My Preferences," then go to the "Editing" tab. There you will find a drop down menu for the "Preferred Editor." Change it to the Classic Rich Text Editor. That will give you the Visual Editor feel while also working. (That's the exact same thing that appears when you edit a page and click the drop down menu and then Old School Antic.)
