Hello,
please see secure note for login details etc…
i had some problem adding simpale javascript code in to your theme with cornerstone so one of your support helped me here: https://theme.co/apex/forum/t/popup-modal-iframe-is-it-possible/20727/10
so one of your support guys added the code with Raw content but what happens then it is not possible to edit tha page any more with cornerstone:
i try to edit this page https://goo.gl/Qhiu3Y1 in corenerstone, and as you can see is not possible.
any ideas why?
