Content missing from site

Driving me nuts now. Have been trying to eliminate the problem but getting nowhere. An email was sent to Cloudflare support days ago but no answer and took a few days to be able to post a subject here after joining the community.

Have Max CDN on the site as well as Cloudflare. Problem seems to keep coming back to Cloudflare.

It seems to only be a problem on a desktop, no problem on mobile device.

Thought it could be to do with the newer SSL certificate, is there anything I have to do on Cloudflare with this?

Never experienced this issue before, I am pretty sure it has something to do with a compatibilty between Cloudflare and Max CDN somewhere.

Only problem I picked up on devtools is it seems the stylesheet isn’t loading.
