Page builder doesn’t work
In WordPress 4.9.6, the tinymce plugin included in WordPress was modified. This unfortunately, breaks the Zion Builder and you wont be able to use the pagebuilder for elements that have a visual editor option type.
In order to resolve this, we’ve released a new theme update that includes a fix for this. You will have to update the theme to the latest version ( v4.15.17 ) and clear your browser cache.
