Class 'SGalinski\SgAccount\Utility\ExtensionUtility' not found
I'm using the free version of the "URL Redirects and Page Not Found Handling" extension (version 3.0.4) with TYPO3 9.5.5.
I configured a "not found" page by selecting an existing page in the page tree.
I get the following exception if I call an non-existing URL (example: /asadf
)
