I just installed the updated theme yesterday and am now finding this error.
It may not be because of the theme, but I noticed it at the same time.
This page uses a “section” under the title and is giving a strange other color.
If you notice, the page is also not centered, extending to this same distance.
Please see the photo and visit the page to see what I mean, as it is difficult to explain.
I hope you are well today and thank you for your question.
Please clear the autoptimize cache that you are using on your site and temporarily disable it along with any other cache of any so that I can troubleshoot it.
Please make sure you are using below latest version of theme.
Please login to access this file
Then please edit that section and remove the background color and box shadow applied to it as displayed in the attached screenshots.
