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.
Could you please share your website and feed URLs so we can check? You can add it in the sensitive data section

It is completely secure, and only our support staff has access to that section.
Looking forward to helping you.
Thank you.
Hello,
I checked your RSS page and it seems to be loading fine as I checked it in an RSS feed validator and it returns with no issue: https://validator.w3.org/feed/check.cgi?url=https%3A%2F%2Fnewsblenda.com%2Ffeed%2F
Could you please clear your website and browser cache and allow crawlers to crawl your RSS feed again?
If that doesn’t work, please try switching to the previous theme again and if the issue goes away, then there’s must be some issue with the new theme you are trying to use.
Let us know how that goes. Looking forward to helping you.
