Website problem after update
EDIT : All sorted now!
After a routine update of the website internals a strange issue has cropped up meaning that the nice links that the system uses are broken. I've had to change it to the default (ugly) link system until I can sort it. So:
Please be aware that until I shout loud enough at the website hosts to get this fixed, all nice links WILL NOT WORK!!!! So please change any that you may have on other sites.
Strangely, you won't have to change them back again once the system returns to normal. the default style links will still work.
(For my fellow geeks; the mod_rewrite module has not only been disabled but also removed entirely from our server. Very odd!)
