Upgrading your Version of Zen Cart
If you manually installed Zen Cart, instead of using GoDaddy Hosting Connection®, you need to manually upgrade as they release updated versions of the application.
Zen Cart 1.5 supports PHP 5.2 to 5.3. If you are using an older version of Zen Cart, you can use PHP 5.2 to access the site until you upgrade.
NOTE: If you are using Zen Cart schema 1.3.8a, you need to upgrade to 1.3.9 before upgrading to version 1.5. Otherwise, you will get errors.
If you have issues connecting to the admin area, or if the application won't let you stay logged in to the Admin area, refer to this Zen Cart help article.
