Problema con installazione Mchat 1.3.5

Salve a tutti, ho scaricato Mchat 1.3.5 dal sito ufficiale di phpbb, ho seguito tutte le istruzioni presenti nel file install.xml, però quando vado a usare il file mchat_install.php mi restituisce l'errore Fatal error: Cannot redeclare deregister_globals() (previously declared in /membri/cosafareper/forum/includes/startup.php:47) in /membri/cosafareper/forum/includes/startup.php on line 114



il codice del file è questo.

Ho controllato se avevo ridichiarato la funzione in altri file, ma l'ho fatto solo qui. Come posso aggiustare?
