Zen Cart 1.5.4 Patches
Updated: January 5, 2015
Upgrading from an earlier versions of Zen Cart to 1.5.4 requires adding new files and new versions of existing files to your Zen Cart installations. You can do this using our patch files for the older versions of Zen Cart. There will also be files that should be removed.
If you have modified any of the existing files included in the patch you will need to reapply those changes to the new files, you can check for modifications by comparing the files in the existing_files folder with the files on your website. Make sure to rename the admin directory in the new_files folder before copying the files.
You will also need to upgrade the database, which can be done through the Zen Cart installer found in the Zen Cart 1.5.4 full fileset.
In Zen Cart 1.5.x the HTMLarea text editor is no longer included. The CKEditor Plugin for Zen Cart can be used as a replacement for this.
