[{“insert”:"Hi, as recommended I use Chrome as Browser and I have reloaded the Browser, removed the cache, but still only a blank screen after the PDF. I only see the “Reset” and “Previous” and “Next” Buttons. When I press Reset I got the message “Are you sure”, but again only a blank screen? Can you please advice how to debug and fix this problem?

Hi Henrique, Thanks for the reply - I got the same error in the Console Window of Chrome if I press the “Reset” button - not sure if this is “normal” behavior or related to the problem I have. May I ask a question. Can you run the Lab exercise right now? Regards, Ralf ---
