Can you post a configuration report
And do you sometimes use extensions like K2 ?

I am not using K2.

I think it may be because of the outdated Blue-Eagle template (version: 1.6.3)download the latest version (version 1.6.7 )
www.kunena.org/download/templates/blue-eagle
and use the standard  joomla templates for a test

the template is not the issue. i changed it to another and my original problem is still there. any other ideas?

Go to the Joomla Global Configuraton (System tab) and enable the debug mode, and on the Server tab set the error reporting to Development. Then try to submit a topic.
Maybe there will be a more accurate error message.
