Non-Www Not Auto Redirecting To Www

Please check in admin->Settings->General:

WordPress Address (URL) and Site Address (URL) and add www in the URL.

This has already been done and issue still occurring.

But when i Clicked the Url: https://doctorofcredit.com it is taking me to https://www.doctorofcredit.com.then what is the issue here?

No, it is not redirecting properly (it seems to sometimes work, which might be what happened to you?) I have a redirect in place, but no idea why it’s not working. Google analytics also tells me there is a problem with redundant host names (same issue non www isn’t redirecting).
