e.ajax is not a function

Hello,

Im getting a weird message in the console when uploading files, as a result the files dont get uploaded and arent attached to the email,

e.ajax is not a function https://www.restore32.co.uk/wp-content/plugins/drag-and-drop-multiple-file-upload-contact-form-7/assets/js/codedropz-uploader-min.js

Ive tried disabling all other plugins but no luck, tried also jQuery migrate incase but again no luck, anything else that could be causing this conflict?

Cheers

Josh
