Wordpress LScache Plugin: enable Guest mode and Gest Optimization get error gtmetrix
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, when I turn on Guest mode and Gest Optimization I get this error in Gtmetrix. If disabling the options I can test the site as normal. Analysis Error Lighthouse Error: The page did not paint any content For more details on common Lighthouse errors, read our guide. This might be caused by Guest optimization. GTmetrix simulates an user browser, but it seems this simulation is not really safe. For testing disable Guest optimization and try again. After enabling Guest mode and Gest Optimization I cannot check performance in GTmetrix and PageSpeed Insights due to error but can check in Pingdom with better score result. However, after disabling Guest Optimize as you said it works. But the thing is that I need other people to check my site performance too without disabling Gest Optimization. What to do? Thank you. Im a new user and try to use your plugin. What to do? Ask GTmetrix to better simulates real user browser, but GTmetrix wont do that. Why? GTmetrix measures on network level and measures the loading time, not the display time . That is the big difference between GTmetrix and Google Pagespeed. Pagespeed dont measures loading time and cant do that, because it measures the display time. The display time measures how long it takes until the browser window is painted AFTER all data has been loaded from server. This is not comparible with the loading time like GTmetrix does it. You understand the difference? I think I understand some but not absolutely. Anyway, I can now test in GTmatrix too and get A score. Just rated your plugin 5 stars. Thank you! In easy words, each test provider tests different and uses other facts. The one how fast you can run and the other one how high you can jump.
