Hi,
There are probably some duplicate SEF URLs created for Kunena home page. Find the SEF URL for your Kunena home page in JoomSEF's URLs Manager and check if there are duplicates created for it. If there are, pick the one with correct Real non-SEF URL and set it as Active by clicking the icon in its Active column.
If you need help with that, you can purchase 1 hour of our support time and we can check the problem directly on your server. See: www.artio.net/e-shop/support-services/joomla-related-support-1h

How do I prevent to create more duplicates, my forum has over 100.000 pages and all have duplicates non sef urls...

Hi,
Please post some examples of duplicate URLs - their SEF URL and Real non-SEF URL. Thank you.
