Question I got blank page when I tried to open my forum

My forum ( www.joomlagate.com/forum/ ) was built with Kunena 1.6 DEV version, build 3864.

This morning it can't be open. When click on the forum menu, I got blank page.

Then I downloaded the latest version from SVN and upgraded my forum to build 3867.

Now, this blank page problem still exists.

I had tried to enable debugging mode and error report, but no error message there.

Below is my forum configuration info:

Could you please help me to solve this problem?

Thanks.

update:

I noticed that the "Recent Topics" page can open:

www.joomlagate.com/forum/latest

But I can't open the forum index page:

www.joomlagate.com/forum/

Can't understand this problem.

Update: I had downgraded my forum to Kunena v1.6.1 stable, but the blank page problem still not solved.

Very confused now, don't know why.

Hello,

looks like a SEF problem, you are using ARTIO JoomSEF and you had problems also with Kunena Menu.

We recommend to use Joomla build-in SEO. Disable JoomSEF and clean cache then check if problem persist.

Regards

Now I have disabled SEF for Kunena commponent, use non-SEF for this component.

But this blank page issue still not solved.

Please go to my website and click on the forum menu (the fourth on the top navigation menu, the only one uses non-SEF URL).

Site url: www.joomlagate.com

Thanks.

Hello,

Enable debug mode in kunena and Joomla! configuration panel, if that help.

Look also, in php and apache log if you see some errors.
