## The action "..." is not allowed by this plugin. {#the-action-is-not-allowed-by-this-plugin}

-   Check your `configurePlugin()` configuration
-   Check if you have a `Resources/Private/Templates/{controller}/{action}.html`
    For details, please see [https://forge.typo3.org/issues/31322](https://forge.typo3.org/issues/31322)

```
\TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin(
    '<ExtensionName>,
    '<PluginName>',
    [
        \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](https://docs.typo3.org/c/typo3/cms-core/10.4/en-us/Changelog/10.3/Deprecation-89463-SwitchableControllerActions.html)

```xml
<switchableControllerActions>
  <TCEforms>
    <label>LLL:EXT:kofomi/Resources/Private/Language/locallang_be.xml:flexforms_general.mode</label>
    <onChange>reload</onChange>
    <config>
      <type>select</type>
      <items>
        <numIndex index="0">
          <numIndex index="0">LLL:EXT:kofomi/Resources/Private/Language/locallang_be.xml:flexforms_general.mode.eventgroups</numIndex>
          <numIndex index="1">Events->list;Events->show</numIndex>
        </numIndex>
        <numIndex index="1">
          <numIndex index="0">LLL:EXT:kofomi/Resources/Private/Language/locallang_be.xml:flexforms_general.mode.persons</numIndex>
          <numIndex index="1">Persons->list;Persons->show</numIndex>
        </numIndex>
      </items>
    </config>
  </TCEforms>
</switchableControllerActions>
```

or

If you tried using FlexForms with `switchableControllerAction`
this overwrites your `ext_localconf.php` even if you delete the Flexform
and the link in your `ext_tables.php`. To work with your extension again
edit the table `tt_content` and search for `switchableControllerAction` in the column
`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.
