Question After Installation registered users only see a blank page instead of post

Hi,

the installation was ok.
I use jommla 1.5.10, php 5, and legacy mode,plus community builder.

so first when I clicked to get to my forum I saw juts a blank page.
i fixed that somehow, then there was a blank page when i clicked on a post.
I deactivated the System SEF Plugin in joomla (dont know what it is), but then i could see posts.
now the problem ist, that i still get the blank pages when I'm logged in and click on a post.
So has anybody an idea whats wrong?
what system plugins have to be activated and deactivated?

Or is there maybe one forum component for joomla 1.5?
Thanks

Hi, please have a few hours patience. Today two new Kunena versions will be releaded (1.0.9 - legacy and 1.5.0 native) and i am sure, that that problem should be fixed than.

i think the 1.5.0 native version is an alpha-release ! not NOT TO BE USED ON LIVE SITES !

I don't know exactly. Look at the top under this url:

Oh, i guess your are right:

www.kunena.com/forum?func=view&catid=2&i...it=10&start=30#10212

We are planning to release K 1.5.0 Alpha later this week, together with Kunena 1.0.9 (Service Release).

Native 1.5.0 seems to be alpha, yes. But legacy 1.0.9 is stable.

that's a goof thing to hear, that there will be something soon for joomla 1.5.10 but I need something right now, or to fir that problem.

Please help.

Thanks

Jens2323: I think you should try to figure out whats making your trouble with Kunena 1.0.x, because it can take some time before Kunena 1.5.x comes in a stable release.

If I understand you correct the problem only appears when users are logged inn? Correct? Then you have to figure out what is different on your site when your are logged inn and not. Is there any module or plugins that only appears for logged inn users? Does the problem all types of users, user, admis etc?
