Hello,
I notice a bug in the Footer of the Wimble template only when we display a blog post.
The Footer is set to full width and the interactive menu too if you have defined this menu by default on the whole site.
At first I thought the problem was only on my site, but when I checked the demo version on your site, it's the same.
I am currently working on a new version of my site, here is an explicit link: https://v2.kawuk.com/wimble/the-start-up-ultimate-guide-to-make-your-wordpress-journal
