Hi,
I have downloaded the last version of Visual composer and now when I want to add a new element and I choose ‘Single Image’, in my browser, in my console I have this error ‘Uncaught TypeError: Cannot read property ‘call’ of undefined’ in the backend.min.js at this line _.isString(rules.callback) && window[rules.callback].call(this) (1391)
And it’s impossible to save the changes because when I click on ‘save changes’ button, the window stay on the front of my window and nothing is saved.
Could you please tell me how I can resolve this problem?
Regards,
Richard
