changing the name of the root folder causes problems

[ali_hijazi]

Hello

We have QlikView server installed on Windows Server 2012

in the Web tab of QllikView web server node, we changed name of the root folder from QLIKVIEW to MLHBI as shown in the image attached

and in the authentication tab we set the LogIn address to custom form and changed (check attached image)

Now to access the access point we put http://IP-ADDRESS/MLHBI

we are redirected to to the login form; we supply the correct user name and password however when we click the submit button we get the page not found error message and still in the address bar we get QlikView in the redirection parameter of the QueryString

but we reset these setting everything works just fine

Please advise
