Thank you for detailed information. There was a problem with load_template() function with WordPress versions older than 5.4.0.
Please make below changes on your website. If everything will work, we will release an update with this fix. Please replace render() function in wp-content/plugins/xml-sitemap-generator-for-google/includes/Dashboard.php file:
public static function render( $template_name, $args = array() ) {
load_template( GRIM_SG_PATH . "/templates/{$template_name}", false, $args );
}
to this one:
public static function render( $template_name, $args = array() ) {
set_query_var( 'args', $args );
load_template( GRIM_SG_PATH . "/templates/{$template_name}", false );
}
Will be waiting for your reply ??
