Hi,
My blog posts (made with Single Layouts) and my footer has one thing in common and that is a social media link to LinkedIn. That link blocks Cornerstone from loading the single layout and the footer builder. If I remove the links - it loads fine. I’ve had this issue before - some years ago, but then it dissappeared and now it’s back.
I thought it was due to some caching but even after disabling WP Rocket and clearing my browser, it still doesn’t work - and it’s the same on some of my clients sites.
On all my blog posts (see this as an example) I have a small author section where the link is present, and in the footer it’s brand icons.
Would you please log in and investigate?
