I upgraded to 1.0.0 using bin/installto.sh. Everything went fine, including the database upgrade. Clicking 'About' in Roundcube reports that I'm running 1.0.0 now. However, when I try to send a message it's stuck on Sending... in the Larry layout. I'm using a dovecot/postfix combination on RHEL 6.5. Server works fine and I can send and receive from Mail.app.
I'm unsure of what config options may cause this or have been upgraded. I've disabled some plugins to try to test that it's not a plugin issue and the problem persists.
/var/log/maillog and /var/log/messages have no Roundcube specific errors. /var/www/roundcube/errors/log doesn't have any *new* errors, and was last updated in 2013.
Where could Roundcube be sending its logs now and how can I find out why it's not sending?
Thanks!
