My entire site is accessed via http, not https. However, hummingbird adds https to the relative paths in the css files, when it parses them and replaces relative with absolute. I think this is a bug. I also fixed it manually, but a next update would lead, again to errors.
Hello!
This is not solved. I am having the same issue. But in my case, relative paths are replaced with absolute ones with “https”, but my site is not accessed via https….
This leads to errors in Chome
