Navigation problems in safari

I have been working on a redesign for my website but the top right navigation is reported to have problems in Safari, any ideas how to solve it?

Link to page

Hi - top right nav loads fine for me in Safari and Firefox but the links don't work in either. Message I get below -

When you say reporting an error in Safari what do you mean exactly?

Internal Server Error

The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, webmaster@intelligent-studios.webmaster-files.com and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

I meant the look of the navigation. The website isnt live yet therefore no links work at the moment.

looks identical in safari to me.
