Empty Mail List Pane - Mailbox is Empty in IE

[dasbkp]

RC Version : 0.8.4
Database : My SQL 5.2.44
IMAP Server : hMailServer - 5.3.3-B1879

Today, When i signed into my mail box, found the message "Mailbox is Empty" in IE. Refreshed so many times, Clicked on "INBOX" & "Mail" link, but the same result.

The left Pane was showing everything perfectly like "Inbox 2410" and other folders as usual, except the Mail List Pane empty with status message below showing "Mailbox is Empty".

Went to Server by "Remote Desktop" and there signed in IE and it was running without any problem. So, i thought the problem behind this is IE got some problem and stopped displaying the Mail List. So, i tried everything in IE to reset to default with all history, cookies delete/reset. Still the same problem.

Tried in Chrome, Firefox, it was fine.
I can re-install IE or by any other means can solve the problem. But want to know what causes the problem in IE, so that easily i can solve the problem of all other user's in future(if someone ask me when he/she will face the problem) and for me now.

My only though would be that Javascript was turned off, the behavior sounds right.

Activex Plugin support, Active Scripting, Scripting of Java applets are ON.

What about Javascript? Not sure where IE hides the option for it.

I'm having this empty folders (not Inbox only - Drafts, Junk, Sent & Trash too) in all browsers (IE8-IE9, Firefox 16 trough 20, Chrome).

System is Ubuntu 12.10 x64 with:
- MariaDB 10.0
- Apache 2.2.22
- PHP 5.4.6
- RoundCube 0.8.x latest build upgraded to 0.9.x latest build
- Postfix 2.9.3 / Courier-POP 0.66.1 / Courier-IMAP 4.9.1 (0.66.1)

During configuration (before I set $rcmail_config['log_driver'] to syslog) I got this error in my logs/errors file:

Code: [Select]

[11-Jan-2013 01:48:49 +0200]: DB Error: Configuration error. Unsupported database driver:  in /var/www/webmail/program/lib/Roundcube/rcube_db.php on line 75 (GET /webmail/index.php)
Is MariaDB supported as a db engine? Can this issue be related to that?

MariaDB isn't supported but I think it would work if you use the mysql driver.
