Wordpress LScache Plugin: Guest Optimization cause SPEEDINDEX_OF_ZERO
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, Im actually testing LSC to replace my actual cache plugin ( wp rocket ). When activating guest optimization I have an error on PageSpeed : SPEEDINDEX_OF_ZERO Like Chrome can not make a capture of the page. The guest optimization is changing my score from 70 to 92 on pingdom tools, so clearly it is a needed option ! What can I change to prevent this error ? NEVER test your page with Pagespeed if Guest Mode is enabled. Read this to get more information about Guest Mode. https://blog.litespeedtech.com/2021/06/01/guest-mode-for-wordpress-in-lscwp-v4-0/ As simple as that ! Thank you
