Thanks for responding. This is the code from the template. The underlying code has nothing to do with the domain registration. This looks like a strange issue to me as well. I did a source-code comparison with and without “www” and its way too different. You can try it on my domain mindsbeyond.in
Am running wordpress in my google cloud vm and using google domain. i manage handful of few other sites in the same way and no issues. it kind of suggests me that there might be an issue in the template. however i will check from my end.
