Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Since that file is outside of your installation, no plugin can minify it, that is why no plugin is being able to optimize it.
Looking forward to helping you. Thank you.
So what should I do know?
Hello,
You can ignore the failed test. The alternative would be to get rid of WP Stats but that might not be possible if you want to use it for tracking.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
