Check your browser console (Command + Alt + J on Mac, or Control + Shift + J on Windows/Linux). If you see any errors, this could be caused by a conflict between Elegantt for Trello and other Chrome extensions.
In this case, you need to disable your other Chrome extensions.
If there are still errors, try again and send us a screenshot of your browser console (Command + Option + J on Mac, or Ctrl + Shift + J on Windows / Linux).
You can contact us at [email protected] and we'll transfer this at our Technical Team.
Feel free to email us your questions and we'll be happy to answer :)
