Sorry to pull the plug on the Ghost of Plug One (to make a bad pun), but maybe you should have that plug and lamp checked by an electrician. The ceiling fan in my dining room developed the same problem about a week ago, and my uncle (a retired engineer) thinks it could be due to a short circuit in the fan's motor that could be arcing/sparking randomly. He advised turning it off at the wall switch and pull chain until he checks it out this weekend.

Good advice! Pretty sure it's an APP error though, but don't tell my daughter that!
