Cisco WLC custom web auth problem

[Augustgood]

Hi,

I have configured Cisco WLC 5508 with a wired guest lan and a custom web authentication, i have downloaded the web-auth bundle on wlc.  I receive the splash screen but when i insert the credential or logout i receive an undefined page. If i use internal web, work perfectly...

this is my environment
wlc 7.6 with custom web-auth bundle installed

Who can help me

I hope the pre auth acl is defined to access the server
