Question Remove Topic icon and yellow code box

I am trying to remove the 2 things in the red rings on the image.

You can remove the topic icons with the following configuration setting:

Forum Configuration » Frontend » Look and Feel » Selectable Topic Icons = No

You can remove the BBcode context help information by adding the following lines to your Joomla site template:

#Kunena td.kposthint {
display: none;
}

I am using 1.5.9, Since the SEF would not work in the new edition.

You asked your question in the K 1.6 Common Questions category. The solution I have posted will not work for you.

There is a configuration setting for K 1.5 (I don't remember right now what it is - you should be able to find it yourself) that controls topic icons.

The BBcode context help ... that's something you should be able to figure out with Firebug.

K 1.5.9 is not a supported version. You should upgrade.
