The general advice that I got and which still works is to do it in the CSS. Hide it through the CSS. I think I did it by going to the Backend Pages. Clicked on the Templates link (on the right hand side you will see it), clicked on the Default Template (the one used for all pages), then on it, somewhere at the bottom (out of the way) I dropped a CSS control (from the Scripts and Styles drop-down), when editing the CSS control I have clicked on Write CSS and wrote this:
Save, Publish, and see if it worked. You might need to refresh the application and all the rest, to make sure the CSS is registered.
Let me know if it works, if it doesn't then I will try to remember how I did it.
