If you go to the top right where your user name should be displayed, and then "Edit Options", there is a board style at the bottom right. Make sure this is set to duende.

It just changed a couple of days ago, without my doing anything. My name and the drop down menu are now located on the left!  I assumed (rightly or wrongly) that it was something that had been done elsewhere. 

I checked the style and it was set to duende.  I changed it to default - which is much better. 

I then changed it back to duende, but it's still horrible (see screenshot, everything is cramped up) so I went back to the default style.
