I have installed the theme "Kute Boutique" on a fresh new install of Wordpress with the default plugins required by the Theme.
After clicking on new article, template, "Default Template" Tab, and on any of template in the Tab, I have the following error message raised by WPBackery (See screenshot attached).
Please could you advise how I could resolve this issue?
(To note, I am using this feature on another website based on another plugin without any issue0
Thanks and regards
