I have been using a smartform with a client site. No issues that I heard of. Had to change the form recipient email - entered, validated, and applied. Moved the page over to the server, and now it is not functioning.
Also, the form should redirect after submission when processed; it is not doing that either.
That was the issue - Inside the assets, there is also another folder, embed/js folder, with another smart-forms.min.js file, so I just moved everything over to the server.
It works now, and it completed a verification before sending.
