When i submit the Quform form on my WP website (YellowProject Theme) nothing happens… Inspecting with Chrome and Firefox it seems to have a problem with jQuery (main.js ?), especially an $.handleError.
I have already used Qform with an other website and it works perfectly.
I’ve tried to remove the jQuery Form lines as you said. It seems to fix the form validation problem, but curiously it causes layout theme failures. I finally use the theme’s Form which is a little too basic (no options,etc…)…
