Issues as follows:
1.Pls visit www.joomlagate.com/,then click Joomla论坛（joomla forum),as usually,it should be directed to www.joomlagate.com/forum page,like www.kunena.org/forum
but unfortunately it direct to
www.joomlagate.com/index.php?Itemid=101&...page&defaultmenu=103 equal to www.joomlagate.com/forum/latest .
2.Let's see the home page of Kunena forum www.kunena.org/forum/index ,but on joomlagate ,let's click index , www.joomlagate.com/index.php?Itemid=102&..._kunena&view=listcat ，which shows broken link/blank,so can not
show the sections and categories.
3.PLS HELP US!!! Much Thanks!

Someone mentioned this bug report and its patch:

www.kunena.org/forum/12-community-builde...er-integration#62274

That bug belongs to Kunena 1.6.0 RC3 version, but my forum uses Kunena 1.6.1 stable version. I think this bug had been fixed in stable version, right?

Yes, this has been fixed in k1.6 stable version.

update:

Ok, finally I have to use this method:

1. backup my kunena database tables
2. completely uninstall my kunena, including delete all jos_kunena_*** tables
3. re-install Kunena v1.6.1 stable, it works fine
4. import my saved kunena tables

After these steps, my forum worked smoothly for several days with SEF enabled. I use Index (categories list) as the forum default page.

Today, I went to my forum and deleted a spam post, since that topic has only one post, in face I deleted a topic.

Then, I got blank page for my forum index page again !!!!

Now, I have to choose Latest Topics page as the default forum page, this page can be opened properly.

But I can NOT enter the Index page (categories list) !!!!

I think this must be a bug of Kunena 1.6.1 .

Hope you will fix this soon.

Thanks.

Now, I upgraded my forum to Kunena 1.6.2 stable, but the blank page issue still not solved.

My server admin gave me following error log (from httpd-error.log):

He told me that these error reports ONLY happen when visiting Kunena pages, not on any other Joomla pages.

What does these errors mean? Is this the cause of my blank page issue?

Thanks.

Ok, finally this issue solved. I now post the solution here to help other users who will encounter the same problem as mine.

The server admin of my website found out that, it is the conflict between PDF module and GD Library on the Apache server (built on FreeBSD) that caused this blank page issue.

He just disabled the PDF module of Apache (pdf.so) then everything worked fine.

Thanks for all of you who had helped me here.
