Sidebar issue

Hi, I have again the same problem posted on my ticket of 28 August, probably because I have updated the theme.

In my post list page I have setted a sidebar in the right side of the page (http://imagizer.imageshack.us/a/img924/1742/xnjD0c.jpg), but unfortunately it is always showed in the left side.

Here you can see it https://bit.ly/2CPgYhi

Please can you tell me how did you fixed it, last time?
If necessary now I have setted a child theme.

Thank you in advance.
