I was just helping a client move their WordPress site away from an "internet marketing solution" company to something they could control themselves. The company sent me the files, but not the database dump. When requesting that, it led to a surreal conversation:
Them: "WordPress doesn't have a database".
Me: Yes, actually, it does.
Them: "No, it never does."
Me: Yes, really, it does.
Them: "Well, this one is a simple WordPress site. Those don't need a database".
Me: Yes, it still has one. I promise. Do you have access to a control panel of any kind? Maybe cPanel or Plesk? Something we could get to phpMyAdmin through?
Them: "No, can't you just get the database through Front Page? That's what we use."
Eventually they called around and found someone that could help. At least it ended well, but that's 30 minutes I'm never getting back...
