Top bar lost on upgrade

Hi,

I just updated to version 2.7.7 from 2.5.9 and seem to have lost the top bar with the page menu on my website. Apparently I need to make changes to the style sheets. Can anyone give me any pointers on what changes need to be made where?

Thanks

Is the menu still visible in the HTML sourcecode? If so you'd best comment/disable stylesheet rules until the menu shows. This should help finding out why it isn't shown in the first place...

If the menu is not in the HTML, then look and see if the problem is with your layout. The layout and themes got changed somewhere around that time. So check that you can see your layouts, modules and that modules appear in your layout.
