Minify: On Multi-Domain setup original files not removed

Hi,

we have set up WordPress with Polylang to use multiple domains. On activation of the minification the original assets are not removed thus all code is executed twice (CSS and JS).

Origin URL: https://setonblog-de.andersundseim.net/
2nd domain: https://setonblog-at.andersundseim.net/
3rd domain: https://setonblog-ch.andersundseim.net/

We have tried changing the minify method to disk and to to host the files in a CDN. Neither of both worked. Hope your’ve got an approach to solve this issue.

Many thanks & kind regards
Mike
