Post background colors not showing

Hi There

We recently updated the newspaper theme to version 1.2 and our post background colors and sidebar disappeared.

This is what the article should look like:

https://bbriefdemo.jhnet.co.za/the-importance-of-dressing-for-an-interview/

This is how it looks on the updated site:

https://www.bbrief.co.za/2019/07/17/the-importance-of-dressing-for-an-interview/

When I switch the post template from style1 to default, the background color appears but the sidebar disappears.

The sidebar disappears whenever the article is assigned to more than one category.

Please advise.

Regards
Richard
