Salve a tutti,
stavo installando easyphp perchè ho necessità di fare alcune prove senza internet (devo spostarmi), Ho scaricato i miei file da remoto in locale, ho cambiato i file di connect, ma quando vado a fare la stampa del pdf mi da tutti errori e non stampa nulla... Lo stesso script su internet funziona PERFETTAMENTE... Dove sbaglio?

questi sono gli errori :
