wp fastest cache does not cause any problem. this problem already exists. If you turn off wp fastest cache, you will see that the problem is not fixed.
Not at all, If I deactivate the plugin the problem is solved, the problem exists only when it is activated especially when I tick minify CSS and combine CSS option. so all I am asking now is, what actually is causing the issue because WPFC means WP Fastest Cache right!! if I am not wrong.
If you don’t really know what’s causing the issue then no issues, we can switch to other cache plugins but please don’t post this same reply on every topic of the same issue.
At least try to find out what’s causing it because i can see a lot of people asking about the same issue.
the problem is not solved even though you disable wp fastest cache.

Below is the link to the screenshot which was taken when the plugin is activated, as you can see the wpfc_minified.css everywhere.

my god 🙂 That’s what I’m talking about too. These warnings already exist. wp fastest cache just renames the sources when they are minified.
So, if I clear all those warnings that are already existing, the wpfc_minified warning won’t come, isn’t it?
