I have this problem, but it only exists in IE. Firefox is fine and so is Opera, but bad old Internet Exploder just ain't having it!
My footer.php is present and my settings are for full sidebar action.....Mr Sidebar, come back, all is forgiven!
Additionally, I have deactivated all the plugins on the right sidebar other than the standard tags cloud (which are Amazon Showcase and Events Calendar) and it still didn't show....
anyone got any hints?
if you want to see for yourself in different browsers...fine in em all except IE
