I don't get a message list when using this theme. The ajax loading icon keeps spinning and nothing. I get the list of folders and the top menu but no messages. I would really like to get this to work so if someone can tell me what I need to do that would be great.
I've found that this problem only occurs when horizontal mode is set as the default in the Roundcube main.inc.php file. Ensure that this line is present (as per the installation instructions):
$rcmail_config['preview_pane_vertical'] = TRUE;
That should get rid of the loading icon. When you log in, click "horizontal" at the bottom to switch modes. This is then stored as a cookie so it will remain the same when you log in subsequently. This brings me on to another bug I've found.
I am currently running Roundcube in a sub-directory underneath a Joomla installation. It works fine until the above cookie is set, then I keep getting error 500 whenever I try and access a Joomla-based page. It appears that the cookie name 'layout' is used by Joomla in some way. This occurred using Firefox 3.1b2 and IE7.
To fix it, I've renamed the cookie to roundcube_layout (see templates/mail.html, lines 96, 119, and 152). It might be worth putting this into the next release.
I've also found a slight layout issue in the folders list (see attached screenshot). A few tweaks to the widths in #folder-manager and the #subscription-table entries in settings.css should fix this.
Otherwise, it looks excellent.
