2nd Bug report
When files are processed on a subdomain e.g. xxx.domain.com to be used on another subdomain (with the same main domain name), e.g. yyy.domain.com, there are some broken links. In my case the header background photos used with a Astra theme weren’t visible on the site when viewing on a Android phone or Tab. When the script ran on a local WP setup, they would work on yyy.domain.com. Very odd!
