Brief
We have updated the logic of the script 'admin_cms_layout.php'.
Description
When you delete a layout from the CMS > CMS Layouts page and then go into the layout editor for any page that had been using that layout you get php notice errors due to logic issues.
Solution
Download the updated version of the file:

Further, extract the file into the 'admin' folder of your shop replacing an existing file. Please do not forget to make a backup copy of the current file in case something goes wrong.
