I don't have contact with the person who built this site, and I don't have much experience with programming/modx so I'm not sure where to start looking for the problem. Can anyone point me in the right direction?
Thanks
Version is MODX Revolution 2.2.10-pl (traditional)
The page is badly formed, there is a misplaced <body...> tag. This is probably causing some Javascript to fail. The first thing you have to do is to figure out where that extra body tag is coming from.
