Hello!!

I've got an item in my website which i don't want to be commented, Is it possible to deactivate the comment option for certain items? If yes, How?

Thanks!

you can disable the display of the comments and comments form by editing the item and in the item view hide comments

I was ticking the wrong option..

Thanks William!!!

Hello,

I have a related question, is it also possible to prevent that (unregistered) users add new comments but keep showing existing comments?

Thanks!

Yes, but you will have to make an override and wrap the block that displays the form to submit comments with an if statement after first getting the usertype very similar to the code in this post
