Dear,
It wasn’t fixed, I did all the tests, following your tutorial (which is even wrong, when you click on the “settings” (gear) the form edit does not appear, the correct thing is to click on the submit button to appear)
But I still have the same problem, when I click submit, nothing happens, it doesn’t redirect, it doesn’t create a post, it doesn’t do anything.
I suggest redoing the tutorial, updating.
The plugin idea is great, I would buy it without a doubt, but for that it needs to work.
