the error is not showing up when you disable the Divi theme, I think it is caused by Divi theme,
The error I’m getting
Fatal error: Uncaught Error: Call to undefined function et_builder_i18n() in /home/customer/www/walkgrove.8xcornwall.com/public_html/wp-content/themes/Divi/includes/builder/module/Icon.php:24.
