no, it'a a temporary solution. is the request in administrator/components/com_easystore/src/Helper/SettingsHelper.php
function getPluginSchema: search the file products/easystore/payments.json in joomshaper.com site, when function fetchContent call the file, cloudflare block the request.
So i copy the file payments.json in my site and i change the url in the function.
If i copy the file in: administrator/cache/easystore and reset the code, resolve just temporaly the problem, because if i clean site cache the problem return.
