[PhpBB 3] Problema Wp United allo step 5

Ecco cosa mi esce alla fine dello step 5 quando installo il Wp United:

"The server did not complete the request. It returned a blank page. Please temporarily enable PHP error display so we can see what the error is, or try increasing your server's memory limit. Then, click Retry."

Come potrei risolvere?
