Buonasera,
ho il seguente problema con uno script (visualizzatore della fase lunare) che da quando utilizzo la versione di PHP 7.3.1 non viene più visualizzato,
lo script in php è composto da due file index.php e admin.php e chiedo se è ancora possibile aggiornare il codice per renderlo utilizzabile.

Grazie per l'attenzione.

Riccardo
