My class is having problems getting to pages we created last week. We're using MS Explorer 7 and MS Explorer 8. An error shows up on the main page in Explorer 7 (line 557 char 3 "$" is undefined) and shows up again after logging in (line 2 char 1 'Query' is undefined ... url http://my.yola.com/sites/) Similar errors display in Explorer 8. I can log in using Firefox with no problem; unfortunately, my students do not have access to Firefox on the school network. This problem started on Friday 2/25. Suggestions?
