Problems with Club Together????

ValDa

Anyone not able to negotiate the forum properly?  I can't click on Club Together - it just comes up with the following message in the box immediately under Community at the top right of the pages:

Error parsing XSLT file: \xslt\SideNavigation.xslt

I can hover using the grey dropdown bar - but whenever I go back I have to re-hover each time to get back to discussions.  That's just happened since the 'downtime' this morning.
