"not loaded or no autoloader? Class WapplerSystems\WsFlexslider\Controller\FlexsliderController does not exist"
Solution

  • Do you use typo3 in composer mode? If so, you have to declare extensions that are not in versioning in the composer.json. Otherwise they wont be added to the autoloader. You can do this the following way:

    {
 ...
 "autoload-dev": {
   "psr-4": {
    "TYPO3\\CMS\\Core\\Tests\\": "web/typo3/sysext/core/Tests/",
    "Vendor\\ExtensionKey\\": "web/typo3conf/ext/extension_key/Classes/"
   }
 }
}

    To update the autoloader, the following command must be executed. The additional argument ensures optimization at the same time. The respective classes are loaded faster.

    composer dump-autoload -o
