From a day to morning the Mautic forms disappeared from WordPress.
Does anyone have or had the same problem? After several days doing thousands of tests I have managed to solve the problem but I have not identified it.
After a lot of talking with the hosting provider, they tried to make me think that the problem was in Mautic or Wordpress. They recognized that on his server they have installed software that generates the issue (CacheWall). The question is that I have other installations in the same provider with Cachewall activated and I have no problem.
Someone have Cachewall on your server and Mautic work for you?
I hope we can find the definitive solution.
