[現象] EC-CUBE4　web api プラグイン エラー guard.entry_point key authenticators
上記の "web api プラグイン"を"Google Merchant Center"をインストールする前段にインストールを管理画面の認証キーの登録からはいらなおで、プラグインを探すからインストールし完了したら、管理面に戻ろうとしたら下記エラー表示です。

Fatal error: Uncaught LogicException: Because you have multiple guard authenticators, you need to set the "guard.entry_point" key to one of your authenticators (Plugin\SocialLogin4\Security\Authenticator\Auth0Authenticator, Plugin\SocialLogin4\Security\Authenticator\Auth0Authenticator). in /home/izsh842519ir/e-lifeseed.com/public_html/vendor/symfony/security-bundle/DependencyInjection/Security/Factory/GuardAuthenticationFactory.php:118 Stack trace: #0 /home/izsh842519ir/e-lifeseed.com/public_html/vendor/symfony/security-bundle/DependencyInjection/Security/Factory/GuardAuthenticationFactory.php(85): Symfony\Bundle\SecurityBundle\DependencyInjection\Security\Factory\GuardAuthenticationFactory->determineEntryPoint(NULL, Array) #1 /home/izsh842519ir/e-lifeseed.com/public_html/vendor/symfony/security-bundle/DependencyInjection/SecurityExtension.php(548): Symfony\Bundle\SecurityBundle\DependencyInjection\Security\Factory\GuardAuthenticationFactory->create(Object(Symfony\Component\DependencyInjection\Compiler\MergeExtensionConfi in /home/izsh842519ir/e-lifeseed.com/public_html/vendor/symfony/security-bundle/DependencyInjection/Security/Factory/GuardAuthenticationFactory.php on line 118

pluginの削除をアドバイスいただき、当方htmlでのHomePageつくりはしてきましたが、最近のphpなどにはうといですが、ご指摘のプラグインの削除は、管理画面ではできませんでしたので、FTPでこのドメインのECCUBEの

public_html/var/cache/以下の削除、これでも変化なし

public_html/app/plugin/apiを削除（コピー保存していなかった！）
したら、どうにも致命的に？。以下のエラーです、サイトも同じ。
具体的な回復への修正法をおしえていただけませんか。
