After execution of openvpn-admin/install.sh when clicking on "Get configuration file" in https://openvpn-admin.{my_domain.com}/index.php?install" I can read the following error log from my apache

PHP Fatal error: Uncaught PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'openvpn-admin.user' doesn't exist in {path_to/}openvpn-admin/index.php:18\nStack trace:\n#0 {path_to/}openvpn-admin/index.php(18): PDOStatement->execute(Array)\n#1 {main}\n thrown in {path_to/}openvpn-admin/index.php on line 18, referer: https://openvpn-admin.{my_domain.com}/
