First of all, thank you for the extension.

When installing the current version 4.1.0 via TER on TYPO3 11.5.13 the following error occurs and I get a white page:

Uncaught TYPO3 Exception: Expected to find class "Featdd\DpnGlossary\Controller\TermController" in file "/html/typo3/typo3conf/ext/dpn_glossary/Classes/Controller/TermController.php" while importing services from resource "../Classes/*", but it was not found! Check the namespace prefix used with the resource. | Symfony\Component\DependencyInjection\Exception\InvalidArgumentException thrown in file /html/typo3/typo3_src-11.5.13/vendor/symfony/dependency-injection/Loader/FileLoader.php in line 224.

What could be the reason for this and what can I do?

Hi @the-andyman,

this looks like a composer autoloading issue, have you required the extension properly and have you tried to delete the vendor and extension folder to rerun composer install?

Greetings Daniel

Hi Daniel, the extension was installed via the Extension Manager in the backend and not via composer.

Okay, have you tried to dump autoload in the maintenance module?

Ok, after I deleted the autoload and cleared the PHP cache, the Extension installation works! Many thanks for the quick help!
