Hi folks I have this error:

  1. I created a landing and I get the error below.
  2. I cloned the landing and the page works (like all the other landings
  3. I swapped the alias of the new one with the old one and now the old one works and the new one doesn’t
    Some idea? I solver with a 301 redirect but I will understand what is this
    Thanks
