I believe the error is caused by a large chunk of HTML being compressed into a single line. Without the EOL characters, the entire line is ignored by IE.

The consequence of these errors is that very important pieces of the UI are not being displayed correctly. Things like the Join or Sign In button are not showing, so it looks like the functionality is missing.

I thought I was going crazy until I switched browsers. I am sure other users are experiencing the same issues, especially those who are accessing community from government machines since IE is still the default browser on those machines.
