Results in trello "Invalid return_url" error about wildcard origins

[optimiseddesign]

Is this still being actively maintained? I've found it really useful over the past couple years, but can't get it to work any longer.

Using the hosted version at http://tianshuo.github.io/trello/ , I get the following error;

Invalid return_url. Wildcard ("*") allowed origins are no longer supported. Contact the developer. See https://community.developer.atlassian.com/t/52093
