Drop down menus - nojs

[mk craig 42]

It seems all my drop down menus and pretty much everything doesn't work..
I tried to edit the last template I edited to come up with a fix, but when I click "edit templates" it does nothing... So I can't even get there to revert it, I've uploaded all my clientscript files again, and still no effect...

The last template I edited before this happened was header, however that was 2-3 days ago and it all wored perfectly since, then I login today and it doesn't seem to work, the drop down arrows aren't even there, and when I hoover my mouse over a (what should be) a drop down menu, it links me to here: http://my-site.com/forum/?nojs=1#usercptools

~Any ideas?

Thanks
