Question No text displayed in post

Hello. I have Kunena 1.6 integrated into Joomla 1.5.23. When users add a new post to, the text is not displayed. I am a newbie and do not know where to start troubleshooting. I have attached Kunena configuration output:

Database collation check: The collation of your table fields are correct

Apparently the culprit was a link to a PDF file embedded within the text. The link was tested to be correct. If the link were typed in directly, i.e. not using the add link icon in the editor, the message would not be displayed. If the link were added via the add link icon, then the message is displayed. However, a random link to a website, typed directly into the editor would not cause the same behavior. This seems like a major bug in Kunena or the editor.

Hello,

Can-i see it on your site ?
