white padding content and size adjustment

Hello I just upgraded to the premium version of vantage yesterday. Till now everything is going much easier with adjustment instead of searching for different codes.

However I still have some issues with the white padding on the bottom of the metaslider on the homepage.

I tried all the different options that were suggested here and I still cannot solve this issue.

Here are the issues:

– when editing the sidebar the widgets added here are shown in the bottom white padding. This is the way I would like it to be, only thing is the white padding is taking up to much space and I want it to be smaller.

– The added widgets are shown on the right side in a row I want them to be next to each other. Tried every possible way but this does not change.

– On the left side there is this post widget which I would not want to be shown on the site. I also tried every possible way to remove this but still with no succes.

I hope my explanation was clear and can get some help with this.

Thank you!
