I suspect it's the deployment, even when i turn off the LSCACHE plugin the error persist in Google Pagespeed.
I have 2 websites on GCP with openlitespeed-wordpress deployment:
Both of them get the same error. (even if i turn off the LSCACHE Plugin)
From the other hand, i have another client, i built for him 10 websites on cPanel server with the same "THEME" on WordPress
and they not do this issue on Google page speed test (have sites they identical to what i open with Lite Speed deployment)
So i pretty sure it's the deployment himself (openlitespeed server).
both of the clients sitting on the same machine (e2 – micro from Google Cloud)
they just not the same deployments. (one of the client is openlitespeed-wordpress, and the other client is cPanel server + WordPress open via cPanel interface)
