Hi, I'm getting this:

<a href="<br /> <b>Warning</b>: require_once(/home/mtbiker/public_html/administrator/components/com_kunena/libraries/api.php) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: No such file or directory in <b>/home/mtbiker/public_html/components/com_kunena/lib/kunena.config.class.php</b> on line <b>20</b><br />

It seems that there are some leftover files in your Kunena after update to 2.0.1. We've fixed our extension so it should handle this. Please update Kunena extension and let me know how it works. Thank you very much for your help.

Thanks, working prefectly now :)
