For some odd reason the top menu in my site has started sorting its items in reverse order. flat_top.tpl is not being overridden, and changing the sorting in the admin interface works fine - just back to front. Does anyone have any idea what could cause this?
My apologies. I've worked out what happened, and it wasn't an eZ problem at all - more like a CSS problem: switched float direction. Stoopid stoopid, RTFSC before posting etc.
