Let me clarify at the very beginning: The plugin does what it claims to do: Completely minifiyng the source code. If this is what you are searching for - look no further. HOWEVER. I guess we all agree that the key idea behind minifying is to further reduce filesize and to serve pages faster. This plugin does the exact opposite, as I could verify on several of my wordpress pages, all on different servers and configurations, PHP versions and so on. The calculations done by this plugin are so heavy, that TTFB is pushed up from around 80-100ms to around 1.000ms in some cases, so actually it made the page slower by a magnitude of 10! The tradeoff of a smaller served fileszie is completely eaten up by the calculations this plugin does to reduce the filesize. Deactivating the plugin immediatly boosted my lighthouse score up by around 5 to 10 points. Good idea - but sadly bad execution.

My WP installation is currently running 49 plugins... All in one Minifier Version 0.3 working in spectacular fashion both Admin side and on the front end. No errors/warnings of any kind being logged. Great plugin! Wish you the Best! Hope this one goes FAR!
