@chukster1000, A flawless upgrade from Grav 1.0.10 to could hardly be expected :slight_smile:

Also the issue may be one of the plugins, or the theme. They are probably as old as Grav 1.0.10 is…

  • Did you upgrade the themes/plugins using the command prompt?
  • What does the log file tell you?
    The stacktrace will give some hints as of where the error has been thrown.
