Unable to edit directory path

Put your cursor to the right of the path and continue from there.

The first part of that path is your root directory or your WP install directory. That doesn’t change.

Yes I figured it out before I got your post. I’m such an idiot LOL. One other thing. Why does the file away short code generator not appear in the tool bars when I create a new page?

It’s on the second row by default. Have you toggled open the tinymce toolbars? It’s an icon toward the right end of the first row. Also you have to be in visual mode.
