Joomla 6.1: Product edit form breaks after adding attributes
Posted: 22 May 2026, 09:41
Hello,
after upgrading to Joomla 6.1, the Phoca Cart product edit form breaks only when product attributes are used.
A product without attributes works correctly. But after adding any attribute with an option, saving the product and reopening it, the backend edit form layout is broken.
Console error:
Uncaught Error: The row template is required for the subform element to work
at joomla-field-subform.min.js
Browser console check shows that these subforms have no row template:
- jform[attributes]
- jform[attributes][attributes0][options]
Both return hasTemplate: false.
Environment:
- Joomla 6.1
- Phoca Cart 6.x latest
- Atum administrator template
- Tested in Chrome and Firefox
- Cache cleared
- Tested also with Phoca Cart 5.2.3, issue remains
It seems related to the Product Attributes / Attribute Options nested subform in Joomla 6.
Is this a known issue? Is there any patch or workaround?
Thank you.
