Thread:Project:Support desk/Set version compatibility for extension/reply (3)

Extensions cannot enable and disable themselves. They must be included in LocalSettings.php. If they are, they are enabled, if they are not, they are disabled. With other words: The version check, which I posted above, will only be executed, if the extension is enabled and it might lead to the result that the extension does nothing except stopping execution. You might call this "disabled", but technically the extension must in fact be enabled to do that.
