I installed an app on a client’s Facebook page. I received a distressed call from them the day before a big launch.
Client: I just tried the app, it isn’t working.
Me: I’m looking at it right now. It’s fine.
Client: No it’s definitely not working, it says something is wrong.
Me: I’ve tested it on both Mac and PC, from admin and non-admin accounts. It’s fine.
Client: It’s broken! I’ll take a picture and show you.
They send photo of computer screen from mobile phone. The photo shows “Internet Explorer cannot display the webpage. Diagnose connection problems…”
