During an installation it gives me this error E_DEPRECATED - Non-static method Grav\Common\Plugin::isAdmin() should not be called statically. It is installed locally using WAMP 3.0.6. All other plugins are installed in Admin and working correctly.
I see you already opened an issue on https://github.com/deved-it/grav-plugin-google-maps/issues, that’s the right place to ask for a fix
