Plugin activation error

Hello,

the plugin activation returns me the following error:

“Fatal error: Declaration of WP_Forge\Container\Container::get(string $id) must be compatible with Psr\Container\ContainerInterface::get($id) in /nas/content/live/sillaindustrie/wp-content/plugins/mpress-hide-from-search/vendor/wp-forge/container/includes/Container.php on line 127“

Any suggestion?
