Board3

I installed the Milk_V2 theme along with board3 latest version, and everything works perfectly, except one small thing which I can't figure out how to edit.

On the portal page, the sidebar of the forum gets carried over.

You can see on the website what I mean:

The board index forum right sidebar (the one with the login and TEST box) gets carried over on the front page of the portal.

How can I remove it?

This has nothing to do with the portal!
Please ask the style author.

I did before posting here, and he told me it has nothing to do with the theme and to ask you.

This is a purchased style, we do not provide support for such styles.

All I need to do is block that forum sidebar on the portal page, that's it. There must be something in the portal which "allows" the sidebar to come on the front page. I don't even know where to look at....
