Hello @eutaw,
Thanks for writing in!
Please click the image and find the row element in the breadcrumbs. Once you are in the row settings, you can delete it.
You are having the difficulty of navigating through the elements and the element settings because the site is using a very old X()4.1.1 theme and Cornerstone (1.0.6) plugin. Please be advised that we have released X 7.0.4
and Cornerstone 4.0.4
. It is now available in automatic updates. You can now update to this latest version. This latest release contains fixes for several issues so be sure to check out the changelog (http://theme.co/changelog/).
After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
Hope this helps.
