If you have a caching plugin for your site, clear that cache.
I also suggest you go to the Cloudflare Caching tab and Purge the cache of All Files.
If you have Shell access on your web server, and are lucky enough to have WP-CLI installed, you can run:
wp search-replace http://webshopmechanic https://webshopmechanic
That will update any URLs you missed. I left off the .com for simplicity, as it’s really the first part that needs to be fixed. The search-replace command will accurately replace exactly what you specify.
p.s. I see you’re running Jetpack. I’ve not used that, so I suspect there’s a bit more work to do. It looks like Jetpack is providing some CDN, which should also be cleared.
