Hi !!
Under advisement for another bug, I just pulled the cvs today and now on all the email screens, I have the following:
DB Error in /home/httpd/html/roundcube/program/include/rcube_db.inc (148): DB Error: syntax error
i just uploaded yesterday evening some changes to that file, it works ok on my server, could you please ensure that you have the latest cvs changes ? if the error persists, please take a look at the page source and sent the complete error message.
