Template Onboarding Tasks only works in preview

[RUPEGF]

Hi

I have installed the template Onboarding Tasks, which works fine in preview, but when I try to run it in publish mode, only the first two pages are displayed correctly, then there is just a blank page.

I have not made any changes to the template yet.

Any ideas for a solution. 

I have tried several different browsers.

I have the exact same problem at the moment.
