.. include:: /Includes.rst.txt ========================== TYPO3 Exception 1313855175 ========================== .. include:: /If-you-encounter-this-exception.rst.txt The action "..." is not allowed by this plugin. =============================================== - Check your `configurePlugin()` configuration - Check if you have a :file:`Resources/Private/Templates/{controller}/{action}.html` For details, please see https://forge.typo3.org/issues/31322 :: \TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin( ', '', [ \Vendor\ExtensionName\Controller\YourController::class => 'yourAction', ], // non-cacheable actions [ ] ); or as of extbase 4.7 you need to update your FlexForm with all necessary actions (semicolon separated) in case you use switchableControllerActions: .. note:: As of TYPO3 10.3 switchable controller actions are deprecated. For details, please see https://docs.typo3.org/c/typo3/cms-core/10.4/en-us/Changelog/10.3/Deprecation-89463-SwitchableControllerActions.html .. code-block:: xml reload select LLL:EXT:kofomi/Resources/Private/Language/locallang_be.xml:flexforms_general.mode.eventgroups Events->list;Events->show LLL:EXT:kofomi/Resources/Private/Language/locallang_be.xml:flexforms_general.mode.persons Persons->list;Persons->show or If you tried using FlexForms with `switchableControllerAction` this overwrites your :file:`ext_localconf.php` even if you delete the Flexform and the link in your :file:`ext_tables.php`. To work with your extension again edit the table :sql:`tt_content` and search for `switchableControllerAction` in the column :sql:`pi_flexform` and delete the content of this field and everything works fine again without FlexForm. Another issue that can occur is an issue with `realurl` configuration. It may pass action params as uppercase e.g. 'Show' instead of 'show'. Either fix the `realurl` configuration or allow actions in uppercase. Also, as developer if you changed the FlexForm above, remember to change the plugin configuration on the referencing page as well. The page configuration overrides the plugin configuration and will still have the old (now invalid) value stored.
