Hey Tom
I thought I would try disabling GP blog masonry and columns feature and that fixes the issue as far as the breadcrumbs width of 1080 is concerned however I do want to use the masonry feature.
It only seems to be affecting the footer hooks or the containers that are 1080 in width on my site.
Have you changed anything lately in these GP premium features because I could have sworn breadcrumbs were matching the container width for at least a month or so?
