WP Google Fonts error messages

Hi. These error messages have started appearing in wp-admin on my website:

already defined constructor for class googlefonts in /var/sites/g/growchiswick.org/public_html/wp-content/plugins/wp-google-fonts/google-fonts.php on line 140

Notice: Undefined index: wp_google_fonts_global_notification in /var/sites/g/growchiswick.org/public_html/wp-content/plugins/wp-google-fonts/google-fonts.php on line 1083

I’m using the latest version of WP and all themes & plugins are up to date. Please can you help resolve this issue? Thank you.
