When I try to enable sign up form in web flow and errors such as following shows up

I have done initial testing in MS and all of the checkmarks were cleared but still I am unable to add members through sign up.

memberstack.js?webflow:1 Uncaught (in promise) TypeError: Cannot read property 'length' of undefined

Would be much appreciated if I can ask for advice…

    Hey @astoria17,

    Recorded a quick Loom for you… 15

    There are two data-ms-password attributes on your signup form. One is on the input field (which is perfect) and the other is on the div, so if you can remove that one then you should be good to go!

    all sign up forms need to have a password, members cannot be created without a password or social auth
