Error Message

Other Information

Products php has:
header(“Access-Control-Allow-Origin: https://juniortest-olegs-baranovs.great-site.net”);
header(“Access-Control-Allow-Methods: GET, POST, OPTIONS”);
header(“Access-Control-Allow-Headers: Content-Type”);

But it still doesnt fix the issue.

Both Front end and Back-end are hosted here on different hosting accounts.

CORS is not allowed on free hosting.
That’s why it will not work

Is there a tier on this hosting platform that I can upgrade to that would allow CORS?

No, only premium hosting has no such restriction in place
