  • Probably some of your CSS files contains an invalid line (eg unclosed media query), which can break the Critical CSS generation.

    In most cases it is caused by custom styling, but plugin and theme styles can also cause the issue. Try to exclude files one-by-one from merging: Settings > Optimization > Styles > Exclude Styles, to find what is causing the issue.

    Thanks for the reply.

    Yeah, turning off “Generate Critical CSS” seems to solve the problem. It would be great to make it working. So I should exclude individual css files to see which one is making the break.
