Hi,  
  
  
  
I created a landing page from a HTML source, included a form and published it. When I am opening it in a browser and I am not logged into Mautic, it produces an error 500. If I am logged into Mautic, everything works fine.  
  
  
  
Any ideas highly appreciated.

Hi @PeterTL,

Can you check app/logs/mautic\_prod.php to see what error is generated to cause the 500?

Thanks,  
Alan
