Details
Array of allowed values for the "action" parameter for normal pages.

This method of defining custom actions replaces the deprecated hook. For details about how to migrate existing hook code to the class-based approach, see.

Syntax is:


 * - Load the specified class which subclasses
 * - Load the class FooAction which subclasses Action
 * - The action is disabled; show an error message

Register the new action in extension.json (see schema):

Disable an action
To disable an action just add the following e.g. for the "raw" action to your "LocalSettings.php" file:
