Please fill in any relevant information that applies to you: CentOS Version: CentOS 7 64bit Centmin Mod Version Installed:123.09beta01 Nginx Version Installed: i.e. 1.13.2 PHP Version Installed: i.e. 7.1.7 MariaDB MySQL Version Installed: 10.0.24 When was last time updated Centmin Mod code base ? : Most recent I recently upgraded nginx with brotli compression enabled. Everything works well and can confirm file size is lesser when doing webpagetest.org from original without brotli compression. However, when I test the site with Google PageSpeed Insight, the preview on both desktop and mobile is just plain text. Is that normal? Something wrong with the google test? Anyone else experienced this? Site displays correctly on all browsers. Site is wordpress created using option 22.
