this is a follow-up regarding this article:
We have been in touch with the plugin author and this is now the answer:
the cookie must be prefixed with “wordpress” so that the “once per session” feature can work properly when Cloudflare is enabled. If we remove the prefix “wordpress”, the loader will appear every time the page loads (means that the once per session feature will not work).
Any other solution you could think of how to make this work?
