Nach der Installation bekomme ich einen 500 Fehler und in der Log steht folgendes:

php.CRITICAL: Uncaught Error: Class ‘Elasticsearch\ClientBuilder’ not found {“exception”:"[object] (Error(code: 0): Class ‘Elasticsearch\ClientBuilder’ not found at /www/htdocs/…/vendor/shopware/elasticsearch/Framework/ClientFactory.php:14)"}

Wie kann ich diesen Fehler lösen?

Leider hast du keine Angaben zur Shopware Version gemacht, daher nur bedingte Ideen:

- die jeweilge Shopware Version noch einmal hochladen, darauf achten das alle Dateien übertragen wurden (besser ZIP auf Server entpacken, falls möglich)
- kontrolliere ob PHP Version zur Shopware Version passt

Ah everything fine. It seems that my FTP account did not upload all files.
