[sqlmap-users] [ERROR] possible integer casting detected

[aurel l. <lab...@ya...>]

Hi,I'm trying to run nmap on the Blind SQL challenge from DVWA website (lvl low), and i get this error that i don't understand: 

                    [ERROR] possible integer casting detected (e.g. "$id=intval($_REQUEST['id'])") at the back-end web application


Cheers

N.B: i'm running nmap on Kali 2.0 on a virtual Machine and Metasploitable (where DVWA is installed) also on a virtual machine and same computer.
