editing tools missing, blank post

I am trying to make a blog post as I always do. However, my new post page is missing the standard editing/formatting tools such as B I U undo, etc across the top of the post box. Also, when I cut and paste my post from notepad, the text is invisible, i.e. It is there but can only be viewed when highlighted.

My work partner can view the post when he logs in and has the standard editing tools too. I have tried this with my usual Chrome and also with Firefox with identical results.

Help? Suggestions?

Thanks.
