A client couldn’t access her site in Mexico. I thought maybe it was just her laptop, but she’d try it from someone else’s computer, then an Internet cafe and still nada. Hmm. Couldn’t get into WordPress or even view the site. She could see the site using sites that hide or divert your IP, but couldn’t edit her WordPress site. I tried clearing cache, removing plugins, anything I could think of. Finally I just switched servers (or moved hosts). That did the trick!
