With the latest version of Moments.js the javascript libraries are no longer loading (version 2.0.0):
I noticed in the web blocks that the first characters are "!" instead of the originals. Can this be fixed?
(Check version on the left for what it used to be)
it's only a warning that the source map is not loading. A sourcemap is only required to ease debugging in the browser minimised JavaScript code.
This warning message should not effect execution of the actual momentJs file that is used by the component.
