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.

// In PHP 5.3.0 the error level has been raised to E_WARNING which causes problems
// because we show E_WARNING errors and do not set a default timezone.
// This is because we have our own timezone handling and work in UTC only anyway.

// So what we basically want to do is set our timezone to UTC,
// but we don't know what other scripts (such as bridges) are involved,
// so we check whether a timezone is already set by calling date_default_timezone_get().

// Unfortunately, date_default_timezone_get() itself might throw E_WARNING
// if no timezone has been set, so we have to keep it quiet with @.

// date_default_timezone_get() tries to guess the correct timezone first
// and then falls back to UTC when everything fails.
// We just set the timezone to whatever date_default_timezone_get() returns.

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

Hai eseguito questa parte?
