Test on a clean Trello board

It's possible that SumUp has a conflict with your board. This might be caused by other power-ups, unexpected data, invalid permissions, or a configuration.
Try creating a new Trello board with a few simple cards and lists. Then add SumUp power-up to the board.
If the problem is resolved, then on your problem board try disabling other power-ups, checking all cards for bad data, double-check your shared user permissions, and try re-saving the power-up's configuration settings.

Check your browser's console log for errors

To help diagnose problems, you can check the browser's console log for unusual errors.

  • Open the Developer Console (press F12) and ensure the Console tab is selected
  • Refresh the page
  • Check for any errors in the console. Some errors are normal (see the screenshot below).
  • Check the Network tab for any failed web requests (they will appear in red).
  • Close the Developer Console by pressing F12 again.
