Admittedly, I’m not the most adept at figuring this stuff out. I need some suggestions on where to go to find out more about why I’m seeing what I see.
Well https://seaportwebdesign.com redirects to the www site so there’s a needless redirection in your testing. Also that redirection is currently being done by your origin, but could be done using page rules instead.
Yes, I noticed the redirect – but I’m unsure how to remove/delete/disable it. I have the Yoast plugin and using their redirect manager, I don’t see a redirect from non-www to www, so I don’t have a clue how to remove it.
