@arthur-gareginyan thanks for your solution and taking your time

I solved it in the following way:

1. install the “API KEY FOR GOOGLE MAPS” plugin

This worked for me! Thanks

Hi, I have done the instructions in that post previously, I have whitelist each plugin REST API namespace as detailed in the post but on the activity tab, it shows Request to REST API denied.
I should mention that this website is using Cloudflare, I have already follow the instruccions in https://wpcerber.com/cloudflare-and-wordpress-cerber/
The engine is set in standard mode
