One moment it was working perfectly, I added a sub-page to one of my menu header pages and something broke.
accross the top it should say:
About Us | Community Life | What's On | Resources | News & Views
Instead it's put 'Home' where it should say 'About Us' and then the sub-pages of 'About Us' are expanded at the right hand end of the menu.
If I reorder the sub menus - it works.
Just not sure why my 'About Us' menu is now expanded and become top level!
I've applied a Child Theme to TwentyTen in order to customise the styling - but the header.php is original TwentyTen still.
