Website showing Blank Page

I’d run a page speed test after I activated the plugin and my website appeared blank after the result. I tried using different setup but it’s still the same. I deactivated the plugin and my website returned to normal.

I’m currently using Multisite, I’ll add the plugins that I’m currently using if it’s because of a possible plugin conflict. All I’m looking for is to resolve the leverage browser caching that works with Multisite, hopefully, this will be resolved soon so I can use this plugin.

PS, I uninstalled this for now and will reinstall once this is solved.
