HTTP Error 500 on backoffice modification

[Thibaut Mamascotte]

Hello,

We recently upgraded our prestashop website to the 1.7.5 version. We got no problem during the installation, and upgraded our plugins with 1-click upgrade.

But then we started to get 500 server errors on backoffice modifications, as soon as we touch the cache or any "save" button, it crashes.

This is the error we get when we activate the debug mode :

Fatal error: Uncaught TypeError: Argument 1 passed to PrestaShop\PrestaShop\Adapter\Configuration::__construct() must be of the type array, object given, called in /var/www/vhosts/mascottes-animaux.com/httpdocs/classes/db/container/LegacyCompilerPass.php on line 51 and defined in /var/www/vhosts/mascottes-animaux.com/httpdocs/src/Adapter/Configuration.php:47 Stack trace: #0 /var/www/vhosts/mascottes-animaux.com/httpdocs/classes/db/container/LegacyCompilerPass.php(51): PrestaShop\PrestaShop\Adapter\Configuration->__construct(Object(Shop)) #1 /var/www/vhosts/mascottes-animaux.com/httpdocs/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/Compiler/Compiler.php(141): LegacyCompilerPass->process(Object(Symfony\Component\DependencyInjection\ContainerBuilder)) #2 /var/www/vhosts/mascottes-animaux.com/httpdocs/vendor/symfony/symfony/src/Symfony/Component/DependencyInjection/ContainerBuilder.php(788): Symfony\Component\DependencyInjection\Compiler\Compiler->compile(Object(Symfony\Component\DependencyInjection\Contai in /var/www/vhosts/mascottes-animaux.com/httpdocs/src/Adapter/Configuration.php on line 47

 

If anyone have any solution we'll test out,

Thank you for your time.
