Hello,
Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for any inconvenience this issue may have caused you.
Our tests look for the first image on the page and see if it has the expires headers in the HTTP response which the first image on your page doesn’t have.
However, your server is using a newer implementation called cache-control, but our system cannot detect those and as such it fails this test. That won’t have any negative impact on SEO, and you can simply ignore the error on the SEO Analysis report.
Hope that helps.
Thank you.
Thanks for reply and hope your team may solve detection in next coming upgrade and eliminate showing error in analysis score.
RGDS.
