NitroPack can't be used with another caching plugin that has any of the following features enabled:
Page caching
Image lazy loading
CSS optimization
JavaScript optimization
The overlapping functionalities can cause our optimization mechanism not to work at all.
That's why we don't recommend using NitroPack simultaneously with another caching plugin, like (but not limited to):
Autoptimize
a3 Lazy Load
Breeze
Comet Cache by WP Sharks
Fast Velocity Minify
Hummingbird
JCH Optimize
Jetpack Boost
Litespeed Cache
PageSpeed Ninja
PhastPress
Powerpack (WPTouchPro)
SG Optimizer
Smush (only their lazy load option must be disabled, not the entire plugin)
Swift Performance
W3 Total Cache
WP Fastest Cache
WP Fastest Cache Premium
WP Rocket
WP Super Cache
WP-Optimize (only their page caching must be disabled, not the entire plugin)
