Hi All
I have problem with Content-Type response from the server.
To clarify the problem, I am working on the WHMCS platform, and I have a issue with some features ( like Domain name search does not work ), so that the cause of this problem is that Content-Type should be application/json, but it is returned from the server as text/html; charset=utf-8. as shown in the attached file

The WHMCS support asked me to add this content type to my cpanel, but I have it already there (MIME Types), as shown also in the attached file.

Is there any way to control this Content-Type?
I have access to WHM and to the server level, if that necessary.
Thanks in advance
