G'day, vassilis, and welcome to Kunena.

Are you saying that you cannot post the text "CD/DVD" on your forum because you get an error message?

Can we see your K 1.6 configuration report, please?

Yes I can't use CD/
Where can I find my "K 1.6 configuration report" ?
I did a search in forum and I Couldn't find how or where.

You have Apache module that's preventing you from having some content inside html forms (cd is command to change directory). This is not Kunena issue and it's not even a Joomla issue. It's badly configured (too safe) server.

Do you know how to change this? I have access to server.

Sorry for the delay.

You need to contact the company who sold you the service and talk with them. The same issue should be visible on Joomla articles or in any form where you can type something. Try to log in as user "CD/" or have that inside your password and you will get the same error.
