- Acme Themes

Hello Riccardo,
Can you please try this function.
This is date display function.

if ( ! function_exists( 'supermag_date_display' ) ) :
    function supermag_date_display( $format = 'l, F j, Y') {
        echo esc_html( date_i18n( $format ,current_time( 'timestamp' ) ) );

you can implement this function in the child theme or if you would like to change main theme, the date function is here on, supermag/acmethemes/functions.php, you can just replace the exciting code with the above code.And please let us know if this solve issue.
Note : We are only suggesting to edit in main theme because we will update the main theme as soon as possible with this updates.
Best Regards,
