TOPIC: button in the category opening

I have a doubt: my site is not a neighborhood of news site of my city, and has different categories to install ccoment, aparecen the opening page of each quarter at the end of the introduction of matter, a button to add Comments. I wish it did not appear, but only in the article, how can I do? My site is in www.znnalinha.com.br/portal , and the button of comments you would like to take this in www.znnalinha.com.br/portal/index.php/distritos/ cachoeirinha

Another question: How do I open a ticket in the support section? I not found ......

You can only open a ticket if you have a pro subscription.
If you don't want to show the "write comment" button on the list view, then you need to disable the read more in the layout settings.
