It always says that I have to try to removes the unused CSS. This unused CSS comes primarily from the Quform plugin (the styles.min.css file) (I know some other plugins also put some unused CSS on my webpage, but Quform is the biggest problem, the unused CSS of quform slows down the site the most))
I know that you can’t solve this problem in 1-2-3, but maybe you can take care of this issue in the next big update?
