Cannot load Email messages > blank screen

[harbar1232]

Most thinks work fine, Login, and sending/receiving mail both work fine. but when I click on the mail to view it I get a white screen with Firefox and an error 500 screen in IE.

this is the url of the white screen.
.../webmail/?_task=mail&_action=show&_uid=20&_mbox=INBOX
(insert domain at ...)

I am hoping to find a solution to this problem soon.

Thanks,

EDIT: I found out I can view the email if I click forward, but I would still like to be able to access it normally.

I had the same problem, turns out my php was not compiled with xml.

In roundcube/logs/error I got this: [11-Jan-2009 02:11:47] PHP Fatal error:  Class 'DOMDocument' not found in /usr/share/roundcube/program/lib/washtml.php on line 235

So I did a yum install php-xml and messages started to load properly.
