Strange caching issue

Question

If you view the content of the following file:

http://swiftdigital.ltd.uk/wp-content/themes/bigbangwp_child/style.css?ver=4.4

The content is different to if you view the same file but with 4.5 on the end:

http://swiftdigital.ltd.uk/wp-content/themes/bigbangwp_child/style.css?ver=4.5

The contents of the file on the server are:

/*
Theme Name:     BigBangWP Child Theme
Description:    Edit style.css, function.php or copy theme original files and customize it on your own
Author:         Brankic1979
Template:       bigbangwp
*/
@import "css/colors/color-blue.css";

There is no caching on the server so why does version 4.4 return the old contents of the file?

Your website (www.swiftdigital.ltd.uk) uses Cloudflare. By default Cloudflare will cache JS files and that appears to be what's happening here.

Purging your cache on Cloudflare will fix this.
