[sqlmap-users] Unable to upload stager

[Muto k. <mut...@gm...>]

I have set up a vulnerable php site with MySQL and used sqlmap against it to
test it. All working, except for the --os-shell, --os-pwn and the other os
system access commands. The problem is that sqlmap cannot upload the stager,
even when i specify the correct document root. Why is that happening ?
