Before I installed Hummingbird Pro version, I was using "Fast Velocity Minify", "Cache Enabler" and "Leverage Browser Caching" plugins. My Google Pagespeed Insights scores for both mobile and desktop were 100/100.
But after installing Hummingbird and disabling the above mentioned 3 plugins, my scores have worsen to 72/100 and 91/100 for mobile and desk top respectively. Did I do something wrong? Please advice?
