We have upgraded a clients core Magento files today and found that the sub category’s stopped working.

We had previously added the code creating a static block which calls the sub category groups. Following the upgrade the category area became blank and with a Google search “Magento subcategories not showing” we found many people have the same issue.

For information purposes we upgraded from version 1.7 to version 1.9.

The image shows the actions required to enable the use of blocks.

Click on “System” then “Permissions” followed by “Blocks”.

Create a new Block Name matching the required block used for sub category inclusion. Select “Is Allowed” and then clear all cache and check the site.
