The “Error validating access token” message is from Facebook. It usually appears when you have been logged into Facebook for a long period of time and your session has expired.
The solution is to log out of Facebook, then log back in.
You can tell it’s a Facebook-generated message and not one from CLM because the window has the same blue color like the rest of Facebook, and the company’s “f” logo at the top-left.
