Reference: issues.joomla.org/tracker/joomla-cms/46233 Reproduction in our environment: - Joomla 6.1.0 Stable [Nyota], 14 April 2026 - HikaShop Business 6.4.1 - JCE Editor (latest) - Open any article in the backend, click the "Insert/Edit Link" toolbar button. - JCE internally calls PluginHelper::importPlugin('search'), which loads our two plugins. - Fatal error: Class "JPlugin" not found in /plugins/search/hikashop_categories/hikashop_categories.php:12 The error vanishes immediately after replacing class plgSearchHikashop_products extends JPlugin with class plgSearchHikashop_products extends \Joomla\CMS\Plugin\CMSPlugin in both files (and the same edit for the categories plugin). For full Joomla 6 cleanliness, JPluginHelper should also become \Joomla\CMS\Plugin\PluginHelper and JRegistry should become \Joomla\Registry\Registry. This will likely affect every customer running HikaShop on Joomla 6, and it will hit hard once Joomla 7 ships and the compat6 layer is removed for good. A small fix in your next release would prevent a lot of support tickets. Thanks for the great product — happy to provide additional logs, a full stack trace or test on a staging copy if that helps.
