Linkedin Groups can not be edited ???

Drop down menus in Group directory do not work, and also I can not see my connections (a problem with some of the members here). Can anyone help me understand what is the problem (either with the website or my machine ?
The error I get is: 'Page' is undefined. I have tried updating JAVA & .Net framework as well but to no avail. This happens only for Linkedin pages.
Any help would be much appreciated.
