Quform will not submit: Uncaught type error in jquery.form

[oldtimeguitarguy]

Suddenly, since upgrading to WordPress 3.7.1, Quform will no longer submit. It just hangs – showing the loading animation next to the Submit button eternally. When I open the js console, I see this error (coming from jquery.form.min.js?ver=v20130616:7)

Uncaught TypeError: Object function (a,b){return new c.fn.init(a,b)} has no method ‘Deferred’

I have tried the following:

* Changing email settings from php_mail to smtp mail and back again
* Changing smtp connection type from tls to ssl and back again (I use gmail)
* Uninstalling and reinstalling Quform, then importing my exported forms, and creating new private and public keys for recaptcha
* Changing the jQuery version loaded in the main theme file to match the Quform required version
* Removing the jQuery import line in the main theme file and putting it back again
* Importing the jQuery migrate plugin and setting that to load with the theme file (thinking it might be able to add some potentially-missing deprecated jQuery functionality)

This really needs to work soon. Their site uses another form in a protected page that is the core functionality of their business and I’ve been trying to fix this for about a week now – their entire business is pretty much down at the moment.

Hey there, I figured it out. Apparently the theme itself was forcing jQuery 1.4.2, even though I had added my own script import of a later version right in the header file. I found out where the theme was doing this and changed it.
