de la corriger.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Bien que cet article n'entre pas dans les d\u00e9tails techniques des causes de ce probl\u00e8me et des moyens de le r\u00e9soudre, il devrait vous donner une bonne vue d'ensemble de ce probl\u00e8me pour vous aider \u00e0 mieux le comprendre et \u00e0 en parler avec plus d'assurance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">C'est dans cet esprit que nous allons commencer...<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"what-causes-a-wordpress-database-connection-error\"><span class=\"ez-toc-section\" id=\"What_Causes_a_WordPress_Database_Connection_Error\"><\/span>Quelles sont les causes d'une erreur de connexion \u00e0 la base de donn\u00e9es de WordPress ?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Contrairement \u00e0 certaines erreurs que vous pouvez voir sur un site web ou sur votre ordinateur, comme l'erreur 404 ou un avertissement indiquant qu'une op\u00e9ration ill\u00e9gale a \u00e9t\u00e9 effectu\u00e9e, l'erreur que nous examinons aujourd'hui a au moins un nom ou un message de sortie explicite.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ainsi, lorsque vous voyez le message Error Establishing a Database Connection (erreur dans l'\u00e9tablissement de la connexion \u00e0 la base de donn\u00e9es) lorsque vous essayez d'acc\u00e9der \u00e0 un site web WordPress, cela signifie r\u00e9ellement que le logiciel WordPress ne peut pas se connecter \u00e0 sa base de donn\u00e9es sous-jacente.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Comme c'est dans cette base de donn\u00e9es que sont stock\u00e9s tous les contenus, param\u00e8tres, fichiers et autres du site WordPress, c'est un tr\u00e8s gros probl\u00e8me si le site ne peut pas se connecter. Cependant, m\u00eame s'il s'agit d'un probl\u00e8me s\u00e9rieux, cela ne signifie pas que votre site est irr\u00e9m\u00e9diablement cass\u00e9. Comme nous le verrons dans la section solution de ce guide pour comprendre cette erreur de base de donn\u00e9es WordPress, il est possible d'y rem\u00e9dier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Malheureusement, les causes de ce probl\u00e8me varient et il n'y a pas d'explication unique au fait que votre site web WordPress ne puisse pas se connecter \u00e0 sa base de donn\u00e9es. De m\u00eame, comme il n'y a pas de cause unique \u00e0 ce probl\u00e8me, il n'y a pas non plus de solution unique \u00e0 l'erreur de base de donn\u00e9es de WordPress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cependant, il existe des causes courantes d'erreur de connexion \u00e0 la base de donn\u00e9es de WordPress que nous allons rapidement aborder ici avant de partager quelques conseils sur la fa\u00e7on dont vous pouvez r\u00e9soudre ce probl\u00e8me.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"incorrect-database-details\"><span class=\"ez-toc-section\" id=\"Incorrect_Database_Details\"><\/span>D\u00e9tails de la base de donn\u00e9es incorrects<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">L'une des causes courantes de cette erreur est que les informations utilis\u00e9es par WordPress pour se connecter \u00e0 la base de donn\u00e9es sont incorrectes, notamment le nom de la base de donn\u00e9es, le nom d'utilisateur et le mot de passe.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si WordPress ne peut pas acc\u00e9der au fichier qui contient ces informations - le fichier wp-config.php - ou si le contenu de ce fichier ne correspond pas aux informations d'identification de la base de donn\u00e9es, vous obtiendrez une erreur de connexion \u00e0 la base de donn\u00e9es.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Parmi les causes pouvant entra\u00eener ce probl\u00e8me, citons les modifications du nom d'utilisateur ou du mot de passe de la base de donn\u00e9es qui n'ont pas \u00e9t\u00e9 r\u00e9percut\u00e9es dans le fichier wp-config.php, ou le renommage, la suppression ou la corruption du fichier wp-config.php lui-m\u00eame.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"corrupted-database\"><span class=\"ez-toc-section\" id=\"Corrupted_Database\"><\/span>Base de donn\u00e9es corrompue<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Une autre cause de cette erreur pourrait \u00eatre le fait que la base de donn\u00e9es a \u00e9t\u00e9 corrompue ou endommag\u00e9e d'une mani\u00e8re ou d'une autre. Dans ce cas, WordPress pourrait ne pas \u00eatre en mesure de s'y connecter, ce qui entra\u00eenerait l'affichage du message d'erreur \"\u00c9tablissement d'une connexion \u00e0 la base de donn\u00e9es\" au lieu du site web et de son contenu.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"overloaded-database-server\"><span class=\"ez-toc-section\" id=\"Overloaded_Database_Server\"><\/span>Serveur de base de donn\u00e9es surcharg\u00e9<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Une autre cause de ce probl\u00e8me peut \u00eatre la surcharge du serveur h\u00e9bergeant la base de donn\u00e9es. Dans ce cas, les fichiers du serveur peuvent devenir indisponibles, ce qui provoque une erreur de connexion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Cette cause est particuli\u00e8rement fr\u00e9quente si vous utilisez un h\u00e9bergement mutualis\u00e9 bon march\u00e9 pour votre site web WordPress. Avec ce type d'h\u00e9bergement, plusieurs sites web et leurs bases de donn\u00e9es sont stock\u00e9s sur le m\u00eame serveur, partageant les m\u00eames ressources et augmentant les risques de surcharge. Il se peut donc que ce ne soit pas votre site web qui pose probl\u00e8me, mais plut\u00f4t l'un de vos voisins sur le m\u00eame serveur.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">La bonne nouvelle, c'est que si c'est le cas, il y a une chance que l'erreur se r\u00e9solve d'elle-m\u00eame, une fois que la charge du serveur aura diminu\u00e9.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"how-to-fix-a-wordpress-database-connection-error\"><span class=\"ez-toc-section\" id=\"How_to_Fix_a_WordPress_Database_Connection_Error\"><\/span>Comment corriger une erreur de connexion \u00e0 la base de donn\u00e9es de WordPress<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Si l'impossibilit\u00e9 pour un site web WordPress de se connecter \u00e0 sa base de donn\u00e9es est un probl\u00e8me grave - principalement parce que le site devient indisponible - il est heureusement souvent possible de r\u00e9soudre ce probl\u00e8me.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">M\u00eame si, dans de nombreux cas, vous pouvez r\u00e9soudre ce probl\u00e8me vous-m\u00eame, votre premier r\u00e9flexe devrait \u00eatre de contacter le service d'assistance de votre h\u00e9bergeur. La plupart des bons h\u00e9bergeurs disposent d'un canal d'assistance prioritaire auquel vous pouvez recourir si votre site web est indisponible, ce qui sera le cas si le message d'erreur \u00ab \u00c9chec de la connexion \u00e0 la base de donn\u00e9es \u00bb s'affiche. Mais quel que soit votre niveau de service, contactez le service d'assistance de votre h\u00e9bergeur via le moyen le plus r\u00e9actif, \u00e0 savoir g\u00e9n\u00e9ralement le chat en direct ou le t\u00e9l\u00e9phone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si vous souhaitez essayer de r\u00e9soudre le probl\u00e8me vous-m\u00eame, les conseils ci-dessous devraient vous aider \u00e0 r\u00e9soudre ce probl\u00e8me.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"don-t-forget-to-check-your-backups\"><span class=\"ez-toc-section\" id=\"Dont_Forget_to_Check_Your_Backups\"><\/span>N'oubliez pas de v\u00e9rifier vos sauvegardes<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Avant de commencer \u00e0 essayer de r\u00e9soudre ce probl\u00e8me, assurez-vous que vous disposez d'une sauvegarde fonctionnelle de votre site web WordPress et de sa base de donn\u00e9es. Si vous avez utilis\u00e9 l'un des logiciels <a href=\"https:\/\/memberpress.com\/fr\/best-backup-plugins-for-your-wordpress-membership-site\/\">nos solutions de sauvegarde WordPress recommand\u00e9es<\/a>Dans ce cas, il y a de fortes chances que vous disposiez d\u00e9j\u00e0 d'une archive de votre site web sur laquelle vous pourrez vous appuyer en cas de probl\u00e8me ou si vous ne parvenez pas \u00e0 corriger l'erreur de connexion \u00e0 la base de donn\u00e9es. Votre strat\u00e9gie de sauvegarde doit inclure le test de vos sauvegardes afin de vous assurer que vous \u00eates en mesure de les restaurer en cas de besoin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Si vous n'avez pas sauvegard\u00e9 votre site web WordPress, vous pouvez essayer de contacter votre h\u00e9bergeur pour savoir s'il a effectu\u00e9 des sauvegardes de votre site en votre nom.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">S'il n'y a pas de sauvegardes r\u00e9centes de votre site web, vous pouvez toujours en faire une. Bien que vous ne puissiez pas vous connecter au tableau de bord de WordPress pour cr\u00e9er une sauvegarde lorsque vous voyez le message d'erreur de connexion \u00e0 la base de donn\u00e9es, vous pouvez cr\u00e9er une sauvegarde au niveau du serveur, \u00e0 l'aide des outils fournis par votre h\u00e9bergeur. Ces outils se trouvent souvent dans le cPanel. L\u00e0 encore, contactez votre h\u00e9bergeur si vous ne savez pas comment cr\u00e9er une sauvegarde en dehors de WordPress.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Toutes les sauvegardes cr\u00e9\u00e9es apr\u00e8s l'apparition de l'erreur de connexion \u00e0 la base de donn\u00e9es contiendront toujours l'erreur, mais au moins, si vous faites des erreurs en essayant de r\u00e9soudre le probl\u00e8me, vous pourrez revenir au moment o\u00f9 vous avez cr\u00e9\u00e9 la sauvegarde et r\u00e9essayer.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"fixing-the-wordpress-database-connection-error\"><span class=\"ez-toc-section\" id=\"Fixing_the_WordPress_Database_Connection_Error\"><\/span>Corriger l'erreur de connexion \u00e0 la base de donn\u00e9es de WordPress<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Maintenant que vous avez plac\u00e9 vos fichiers de sauvegarde dans un endroit s\u00fbr et accessible, voici quelques-unes des solutions possibles pour r\u00e9soudre le probl\u00e8me de l'erreur d'\u00e9tablissement d'une connexion \u00e0 la base de donn\u00e9es dans WordPress.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"incorrect-database-details\"><span class=\"ez-toc-section\" id=\"Incorrect_Database_Details-2\"><\/span>D\u00e9tails de la base de donn\u00e9es incorrects<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Comme indiqu\u00e9 pr\u00e9c\u00e9demment, si les d\u00e9tails, tels que le nom de la base de donn\u00e9es, le nom d'utilisateur et le mot de passe, dans le fichier wp-config.php ne correspondent pas aux d\u00e9tails r\u00e9els de votre base de donn\u00e9es, WordPress ne sera pas en mesure de se connecter \u00e0 la base de donn\u00e9es.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pour v\u00e9rifier si cette incompatibilit\u00e9 est \u00e0 l'origine de l'erreur, vous devez localiser et ouvrir votre fichier wp-config.php et v\u00e9rifier ces d\u00e9tails vous-m\u00eame.
