your theme causes the problem, you need to include jquery. This is the case with all standard themes but not with yours.

Try to use a standard theme, this should work unless you did some core hacking..

I actually took the green salad theme and edited that, i have just tested the green salad theme and the plain yoghurt theme and both fail on IE yet work on Firefox...

look athttp://www.v8-automotive.co.uk/index.php?cID=81...

I have tried installing other themes and on Firefox they all work on IE it won't work no matter what theme I use

I just found out a little more, when I was logged into the CMS and editng and viewing the page it worked ok on firefox, if i logged out it then went wrong. SO it seems jquery is working when I am logged in but not when logged out like most viewers.

How do I get jquery working as I cannot see it in any of the themes I tried

I found the problem, I did a compare on two sites I have done and on the not working one it had a code change in the header_required.php file

it called
if ($u->isRegistered()) {

Not sure why that was in as I havent touched that but its all working now... many thanks
