"An unexpected error has occured."

Hello,
I am also affected by this scary issue.

The same problem occurs :

  • On a fresh OSX Chrome profile (so no plugin or nothing) when trying to log in on the website.
  • Same problem on 2 differents macbooks
  • Same problem on Safari
  • Same problem with browser extension.

It all began when this hCaptcha appeared (never seen that before)
