After changing my python and Django version I came up with the error of
Uncaught ReferenceError: addEvent is not defined.
The error took place at my DateTimeShortcuts.js file.
The code raising the error is:
addEvent(window, 'load', DateTimeShortcuts.init);
window.DateTimeShortcuts = DateTimeShortcuts;
This error prevents me for rendering correct a date widget that I am using for my Django app.
Any idea how to handle it?
From commit into Django framework "Fixed #28536 -- Removed old JS cross-browser utilities" you can see that there were changes in that file.
Try to run command that will refresh all static files:
python manage.py collectstatic
