Votre base de données n’a pas été corrompue et votre site est toujours sécurisé. Dans cet article, nous allons vous apprendre plusieurs façons de contourner la boucle Aucune mise à jour requise .
Avant d’aborder toutes les options dont vous disposez pour le réparer, comprenons mieux pourquoi l’erreur se produit en premier lieu afin que vous puissiez prendre les précautions nécessaires pour l’éviter à l’avenir. Jetons un coup d’œil aux raisons de la boucle WordPress No Update Required .
Pourquoi la boucle « Aucune mise à jour requise » se produit-elle ?
La plupart du temps, la boucle WordPress No Update Required est déclenchée en raison d’un problème de mise en cache. Cependant, cela ne se produit pas tout le temps, même avec la mise en cache activée, ce qui indique que tous les types de cache ne sont pas responsables de ce problème. Pour être plus précis, la mise en cache d’objets est le principal déclencheur de ce problème ennuyeux. Mais qu’est-ce que la mise en cache d’objets ?
Mise en cache d’objets
La mise en cache d’objets est un type spécifique de mise en cache dans lequel les requêtes de base de données sont mises en cache dans la mémoire afin qu’elles puissent être récupérées rapidement en cas de besoin à l’avenir. WordPress est livré préchargé avec un cache d’objets intégré appelé WP_Object_Cache .
La mise en cache d’objets améliore les performances d’un site Web WordPress en réduisant la charge de traitement sur le serveur. Cela devient plus important si votre site dispose d’une base de données massive avec un volume de trafic élevé. Dans de tels cas, interroger la base de données peut rapidement devenir accablant pour le serveur. C’est là que la mise en cache des objets aide en répondant aux requêtes de base de données à partir de la mémoire cache au lieu d’ajouter des requêtes au serveur.
Comprenons maintenant mieux comment la mise en cache des objets déclenche le problème Aucune mise à jour requise .
Comment la mise en cache d’objets déclenche-t-elle la « boucle Aucune mise à jour requise » ?
Lorsque vous essayez de mettre à jour WordPress, il recherche un fichier dans la base de données pour voir si WordPress est déjà à jour ou si une nouvelle version est disponible. En raison de la mise en cache d’objets, ce fichier avait déjà été mis en cache à un moment donné, de sorte que le fichier mis en cache apparaît « à jour » pour WordPress.
Ceci est important car lorsque vous essayez de mettre à jour votre installation, au lieu du fichier réel dans la base de données, WordPress lit le fichier à partir du cache. Étant donné que le fichier en cache indique que WordPress est déjà à jour, vous obtenez le message Aucune mise à jour requise , même lorsqu’une mise à jour est disponible.
Si vous êtes dans une telle situation, continuez à lire. Dans la section suivante, nous examinerons différentes options pour résoudre la boucle Aucune mise à jour requise .
Comment réparer la boucle « Aucune mise à jour requise » dans WordPress
Some of the common methods to resolve the No Update Required error are:
- Clear the site and server cache
- Rename the object-cache.php file
- Check for plugin and theme conflicts
- Restart PHP or server
- Contact your hosting company
Let’s go through each of the above solutions one by one.
1. Clear the Site and Server Cache
Since it’s a caching-related issue, the first you need to do to fix the “No Update Required” WordPress error is to clear your site’s cache. This will remove all the cached content that includes the cached WordPress update information. Let’s see how you can get rid of your site’s cache.
Clearing Cache using a caching plugin
The easiest way to clean your site’s cache is using a caching plugin. This step varies depending on the tool you use, but in most cases, it follows similar steps. First, go to your site’s admin dashboard and navigate to your caching plugin settings. Look for the clear cache option to clear all the site’s cache. For more information on how to do this using SiteGround, check out this post. To look for the best caching plugins, have a look at this guide.
However, clearing cache with a caching plugin is only possible when you have access to your admin dashboard. In some cases, the No Update Required loop might restrict users from accessing their dashboards. If that’s your case, you’ll need to do the following.
Clear Cache with WP-CLI
WP-CLI is a command-line tool that allows you to access your WordPress site via a command-line interface. It is a powerful tool that allows you to execute WordPress code without accessing your dashboard.
The first thing you need to do is connect to your server’s command line via SSH and install WP-CLI. From the command line, change the directory to your site’s root directory using the following command.
cd ~/your/website/path //replace it with your site’s actual path
Once you are in the site’s root directory, execute the following command to purge all the cache.
wp cache flush
You can also check out further documentation of the wp-cache flush command on the official webpage.
Clear Cache Using SSH
If you aren’t comfortable using WP-CLI or want to avoid it for any reason, you can clear your site’s cache via the Linux command line. First, you have to connect to your server’s command line via SSH and then use the following command to purge all the cache if your site is using Redis.
redis-cli flushall async
If your site uses Memcached, use the following commands.
telnet localhost 11211 flush_all quit
Clear Cache via Host’s Control Panel (e.g., SiteGround)
Another way to clear your site’s cache is via your host’s control panel. Most hosting companies allow you to do that. This step varies depending on your hosting provider, but most of them follow a similar pattern. Alternatively, you may also ask your hosting provider to clear all cache for you.
For demonstration purposes, in this section, we will show you how to clear SiteGround’s cache using their control panel.
Go to your SiteGround control panel and navigate to Site Tools > Speed > Caching. There, you will find two tabs for Dynamic cache and Memcached, respectively.
Go to the Dynamic Cache tab to clear the site’s Dynamic Cache. It is worth noting that you can clear the dynamic cache for each site individually. Simply select your site, and hit the Flush Cache button.
Next, you need to clear Memcached as well. Unlike Dynamic Cache, you can clear Memcached for all the sites at once. Go to the Memcached tab and hit the Flush Cache button at the bottom.
Now go back to your site and check if the No Update Required loop is fixed. If your site’s issue is resolved, congratulations! You are good to go. However, if it didn’t solve your issue, move on to the next step.
2. Rename the object-cache.php File
If clearing the cache didn’t work for you, you may need to manually discard the object-cache.php file. This file stores all the object cache, so by renaming it, it will drop all the object cache stored.
To do that, navigate to your site’s root directory using the host’s control panel or an FTP client like FileZilla. Once you are in the site directory, go to the wp-content folder and locate the object-cache.php file.
Rename the file to anything else, like object-cache-old.php or whatever you like. This will disregard the currently cached content in the file and will give you access to your admin dashboard.
After that, navigate to your admin dashboard and look for your caching plugin settings. Clear all the site’s cache from the plugin. Then, go to your site’s root directory again, and look for the object-cache.php file. If the file has been recreated, that means that WordPress has discarded the previous file and has now created a new cache file.
Finally, try updating WordPress once again it should work this time. However, if it still doesn’t fix the issue, the next thing you should do is check for a plugin or theme conflict.
3. Check for Plugins or Themes Conflicts
A plugin or theme conflict is one of the most common causes of WordPress errors. It’s possible that one of your plugins, especially the caching plugins, has created a conflict with another plugin or theme. If some other plugin on your site has caching capabilities, that may cause conflicts with your main caching plugin. Regardless of the cause, this can trigger the No update required loop.
To fix this issue, you need to identify the problematic plugin. For this purpose, deactivate all your plugins. If you aren’t sure how to do this, check out our guide on how to deactivate plugins in bulk.
For this demonstration, we’ll show you how to do it from the admin dashboard. Navigate to Plugins > All Plugins, select all of them with the top-left checkbox, set the Bulk Action to Deactivate, and hit the Apply button. This will deactivate all your plugins.
Contrarily, if you can’t access your WP Admin Dashboard, you can still deactivate all your plugins from your site’s root directory. You can access your site’s root directory via your host control panel or an FTP client like FileZilla.
Once you are in the site’s root directory, locate the plugins folder in the wp-content folder. Then, rename it to anything else like plugins-old or whatever you like to disable all your plugins at once.
After deactivating all the plugins, go to your site and try accessing the Admin Dashboard. If you don’t see the No Update Required error, it confirms that the problem lies with a plugin.
Next, you need to identify the faulty plugin. To do this, start activating each plugin one by one until you encounter the error again. Once you have identified the plugin that’s causing the issue, you can roll back to a previous version or contact the developer for technical support. Alternatively, you can try some other plugin to achieve the same functionality. For instance, here is a list of the best caching plugins for WordPress in 2021.
If none of the above solutions worked to fix the “No Update Required” WordPress loop, continue to the next solution.
4. Restart PHP and Server
With the previous methods, most users should be able to solve the No Update required issue. However, sometimes you may face this problem even when you don’t have an active caching plugin installed on your site.
WordPress itself has some object caching mechanism that stores cache without any caching plugin. While the WP_Object_Cache is only stored for a short duration, in rare cases, it might trigger the No Update Required error.
If that’s the case, you can try restarting PHP using your host’s control panel or contacting their customer support team. Alternatively, you can also try restarting your server to clear all forms of cache and will hopefully resolve your problem.
5. Contact Host Provider
So far, we have seen all the possible fixes that you can perform on your end to fix the “No Update Required” WordPress loop. Hopefully, by now, most of you must have been able to solve the issue.
However, if you are still facing the same problem even after trying all the above solutions, it is time to contact your hosting provider. Unfortunately, there is nothing more you can do on your end, so better to contact an expert support team.
Hopefully, your hosting provider has a capable team that can help you find a solution to this annoying problem.
Conclusion
