Drupal (mark a spot)

Ho provato a installare mark a spot che è una applicazione che usa drupal.
L'installazione sembra sia andata a buon fine ma quando provo ad andare alla home page
http://opentreenap.altervista.org/mark-a-spot/

vedo Fatal error: Allowed memory size of 134217728 bytes exhausted

cosa posso fare?

questo è l'unico errore che ho ricevuto durante l'installazione:

An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows.
