The production website's domain was kube57.tv until we finished, changed it to kube57.com -- did not move servers -- followed the instructions in the codex, went in to myphpadmin, changed the URL there, changed it in the settings page within wordpress, and used search and replace plugin and virtually everything is fine.
I'm noticing that some other people visiting the site have complained that some of the pages are giving them "page not found" error (more like "website does not exist") when they go to certain pages. I've asked them to send me the URL of those pages that supposedly don't exist -- they do exist and I can immediately access those pages.
It's been 24 hours since the transition -- I originally blamed DNS propagation but now I'm starting to wonder if it's a WordPress thing. I have w3 total cache that I have emptied all databases/caches and it has not helped.
Any ideas? Suggestions? Things for me to check?
