We are using Joomla 2.5

A client of mine has accidentally selected most of the menu and the submenus and changed the order by clicking one of the blue arrows, now the sub menu is not showing anymore.

I have tried to rebuild the menu

I have tried to clear cache (both mine and joomla)

I have tried to change the order

I have tried to go into the menu module and made sure show sub menu was configured on

Does anyone have any suggestions on how this could be fixed? Would be highly appreciated.

The website is n1golf.com and as you can see none of the menus drop down, and here is a screenshot of the ordering just in-case that might help: <http://d3v9w2rcr4yc0o.cloudfront.net/uploads/stream/2013/01/35569/1d30c79df72549006fdb760569e31399.jpg>

Kind regards
