Hello JoomShaper Support,

I am contacting you regarding the WayneCorp Joomla template: https://www.joomshaper.com/joomla-templates/waynecorp

The template is listed as compatible with Joomla 5 and Joomla 6, but I am encountering a compatibility issue related to deprecated/removed Joomla classes.

Website https://lbcop-j5.ws1.bellosta.fr/

Environment:

Joomla version: Joomla! 5.4.4 Stable [ Kutegemea ] — 31 March 2026 16:00 GMT
PHP version: 8.2.31

The error appears to be triggered by the article_slider addon, although I suspect the issue may affect the template more globally.

Error displayed:

0 Class "JURI" not found

It looks like the template or one of its addons is still using the old JURI class instead of the namespaced Joomla class, for example:

use Joomla\CMS\Uri\Uri;

and then:

Uri::root()

instead of:

JURI::root()

Could you please confirm whether the WayneCorp template and its addons are fully compatible with Joomla 5 and Joomla 6?

Could you also provide either:

1. an updated version of the template/addon fixing this issue, or
2. the exact files and code changes required to make it compatible?

For context, the error seems related to the article_slider addon, but I would appreciate it if you could verify the whole template package for Joomla 5/6 compatibility.

Thank you in advance.

Best regards, Emeric
