Hi,
My site https://thehorsleydirectory.co.uk has recently updated to the latest versions on Cornerstone and ThemeX, but now when I try and drag a classic image element to reposition it on the page I get the following error message:
If I then try and add a different element to the placeholder, the whole body section disappears:
The Cornerstone interface then freezes and I can only exit to the WP Dashboard.
I have only added custom CSS to the X customiser and have not changed any HTML.
Best wishes,
Brett
