I installed and activated the Jetpack Boost plugin. I enabled the Optimize CSS Structure feature. The plugin appears to work and generate the Critical CSS, but I get an error when the JetPack Boost service tries to calculate the homepage loading speed. The error is, “Received HTTP 500 from Boost Service”. I am not sure if the other website optimization plugins are causing conflicts with this plugin. Here’s a list of the other plugins: A3 Lazy Load, Async JavaScript, Autoptimize, Flying Pages by WP Speed Matters, Freesoul Deactivate Plugins, Jetpack, Specific Content for Mobile, and W3 Total Cache. PLEASE NOTE THAT I DO NOT USE OVERLAPPING FEATURES WITH ANY OF THESE PLUGINS! I installed all of them as recommended by a Udemy instructor and only enabled the features he recommended. My goal is to get a higher page load score on desktop/mobile devices, (especially mobile devices) since that score suffers the most! I saw this plugin and thought I would give it a shot, but it does not appear to be working correctly.
