Mi rilascia questi errori (le righe le ho evidenziate in grassetto):
Warning: Cannot modify header information - headers already sent by (output started at c:\programmi\easyphp1-8\www\museo2\mascheralogin.php:13) in c:\programmi\easyphp1-8\www\museo2\mascheralogin.php on line 59

Come dovrei fare per risolvere? So che il problema è dovuto al fatto che headers e cookie non richiedono nessun tipo di output davanti, ma come faccio allora? :master:
Grazie!
