PageLocker not working

Hello,

I need to protect a singe Page with a password, so i try the PageBlocker Plugin.
I set it up like they sad it here: https://modx.com/extras/package/pagelocker

The form to login show up, but when I put in the password an "say" submit...nothing happens. No redirect etc.
What can it be?

It does the same, if I enter the right password or the wrong. It goes back to the form.

(?)

I'm struggling with pagelocker too - anyone have it working on Revo 2.4 or above?

When I enter a password in the relevant Tv on a page I want to protect I just get an empty white page - no redirect to the form resource...

Any help greatly appreciated as this would make my life so much easier on a particular job

Cheers
