I'm using the Forminator plugin for the first time, it's simply stunning and I have been looking for an alternative to Ninja Form and this is definitely it! Amazing!
However, I use Elementor and the Divi Builder for all my sites, I've not tested with Elementor yet but I am building a client site with the Divi Builder and it seems to be automatically killing all of Forminator's styling.
So I reverted the contact page back to using the Classic Editor and instantly the form styling is fine, even with the Divi Builder plugin active. So it looks like if I use the Divi Builder plugin to build a page, it's styles are aggressively overriding Forminators
