Hi Jonas /@layer42
Shopware 6 system requirements state, that you need at least PHP 7.4.3 or higher. As you are using PHP 7.4.23, this could be an issue.
Also, what database system are you using and what version? Our system requirements state the following:
MySQL 5.7.21 or higher
MySQL versions 8.0.20 and 8.0.21 are not compatible due to technical problems in these versions.
MariaDB 10.3.22 or higher
MariaDB versions 10.3.29, 10.4.19 and 10.5.10 are not compatible due to technical problems in these versions.
You can also check the rest of the requirements in our documentation.
Kind regards
Patrick
