Question Nginx + SEO: cannot login and logout from Kunena.

Hi, I would like to ask a question here.
I have just upgrading my Kunena forum to 1.7.2 and my problem is,
I cannot login and logout from Kunena, but only from Joomla module.
How can I resolves this problem.

Using Kunena 1.7.2, Joomla 1.5.25, NginX 1.1.14, MariaDB 5.2.X

G'day, shaifful, and welcome to Kunena.

At the outset I don't know anything about NginX servers or MariaDB databases (which, as far as I know, is not yet at full production stable release status) and I don't know what specific issues these may involve for Kunena. It may help if you posted your configuration report.

it seems that the error only happen when I enable adding suffix to the SEF enabled URL.
When I disable it, the URL becomes /forum?q=/forum, with login and logout, the URL /forum?q=/forum/forum?q=/forum/forum?q=/forum/forum?q=/forum/forum?q=/forum
Is getting longer.

The configuration report
