Firstly, your
moment.min.js is outdated hence the first WARNING, not an error.
Update your .js file, the latest can be found here -
Latest Moment.js File[
^]
Your real error is in
Could not load content for https://xyzhidden.com/assets/css/material-kit.css.map, you have made a reference in your code(which we cannot see) to this map file.
Error 404 means "file not found". Check the path reference to the file and correct your code to read from this file at the correct path.
As this is a site map file that is missing or misplaced, there are a few work-arounds to solve this error -
1. Leave it as is with tons of 404 errors on page load. Very bad idea.
2. Add the outdated missing .map files to the correct folder/s, not really the best solution.
3. Remove the
//# sourceMappingURL=material-kit.css.map lines from all minified(.min) JS files. That means we are not deploying with original/latest file versions. It might be a reasonable solution for now, future is unknown.
4. Download the latest site map files needed, save them in the correct folder/reference them directly to the site supplying the .map file -
<link rel="stylesheet" type="text/css" href="path/to/material-kit.css">
<link rel="stylesheet" type="text/css" href="path/to/material-kit.css.map">
Check the
"path/to/" parts to ensure you have the correct paths specified, whether in your own folder system or the correct https: path.
