Background of the issue:
I added the CloudFlare plugin for caching on my site hidden link. The plugin is currently set up only for the main domain. I want it to work for the other language domains, variscite.de and variscite.it, which are set up using WPML to use a different domain per language.
Symptoms:
The CloudFlare plugin is only working for the main domain and not for the other language domains.
Questions:
How can I configure the CloudFlare plugin to work for variscite.de and variscite.it?
The CloudFlare plugin is officially compatible with WPML. https://wpml.org/plugin/cloudflare/
However, I can see that it has not been tested for several years.
I also think you need to register each of the domains on CloudFlare. Have you done that?
Furthermore, I can see that the WordPress plugin has not been updated for over a year. https://wordpress.org/plugins/cloudflare/ Are you using the above free plugin from the WordPress repository?
Can you please elaborate on the problem you are experiencing?
How have you identified that it is not working for the other domains?
