Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
Could you please try flushing the SEO Analysis data under WordPress Dashboard > Rank Math > Status & Tools > Database Tools and then check SEO Analysis again?

Hope that helps. Looking forward to helping you.
Hi,
thank you for your immediate reply -. now it works!
Regards
Jörn
