Installed update rollup 3 today, after rebooting, got OWA blank screen and an error is IE. If you look at details, it shows:
Line: 7
Char: 1
Error: Syntax error
Code: 0

troubleshooted for a while and ended up calling Microsoft PSS XCSI team. We removed the rollup and the problem went away. Rebooted & Reinstalled rollup and OWA is working fine now. I just wish it didn't take 3 hours for me to figure out this might be the solution
and PSS still wondering why this fixed it.
If anyone wants a log file to help figure it out, let me know.
