It doesn't work on Windows 7 with Chrome, Firefox or IE9. It doesn't work on Windows XP with Firefox. It DOES work on my Blackberry browser. It DOES work when I bring it through a proxy server like kproxy.com.
IMAP functionality appears fine - I can use Outlook as a client. That's what is leading me to think it's some sort of Javascript issue or HTTP protocol issue. From a perspective of blocking - I've disabled all add-ins on the browsers and the Windows Firewall. I'm thoroughly confused. Unfortunately, I'm not a Javascript debugger so it's tough for me to figure out the client side.

Hi All -

I've tried a million things. The Dovecot maildir issues are resolved. No errors show up in the roundcube sql or imap logs, nor in the Apache or Dovecot logs. As a matter of fact, the imap log shows the complete imap transaction as functioning correctly. Yet I can't view the contents of any mailbox or folder - I get "Server Error (OK)" consistently. I'm assuming this is a Javascript/HTTP error of some sort. I'm not sure where the "OK" comes from. Anyway, it's driving me insane. Any suggestions on how to debug this?

If you believe it's a Javascript/HTTP error, have you tested on more than a single client PC/smartphone/browser combination?
