Cloudflare breaks my website. When in developer mode all seems fine. Looking for help

[Dockbuilder](https://www.canadadocks.ca/dockbuilder/main.html) - when I have Cloudflare enabled it doubles up the menu and prevents “hand” icon working. When I set it to development mode (which it is now) the builder works as intended. I tried to add a rule to not cache this link however it didn’t seem to solve the issue.
