Remove Inner sidebar

Hi Supervale,
how are you doing?
Would it be possible to give us URL of your website?
…and tell me what you want to get rid off on your site.
I`ll take a look what we can do
Thanks a lot
Cheers

I went ahead and installed your theme on my test site.
If I understand it well you should do this:

put this code to your Child Theme style.css file
OR
Install Simple Custom CSS plugin and put the code there.

.large-3.large-offset-1.columns {
    display: none;
}

or

.large-3.large-offset-1.columns {
    display: none!important;
}

Hope this is helpful.
Let me know.
Cheers
