Although WordPress is one of the most popular and useful content management systems (CMS), it is not without problems. One of the errors that may appear when using WordPress is the message: "Could not save password reset key". This error occurs when a user tries to reset their password and the system is unable to save the password reset key.
The causes of this error can range from database issues to plugin conflicts. Fortunately, there are specific steps you can take to fix this error. Here are some potential solutions that may help.
1. Check your database settings
The first step is to make sure your database is working properly. This error can occur when WordPress cannot communicate with the database, which means it cannot save the password reset key.
Check the database settings in the wp-config.php file, which is located in the main WordPress directory. All details such as database name, username, password and host should be correct. If you are sure that your data is correct but the problem still persists, it is worth contacting your hosting provider who can check whether there are any problems with the database server.
2. Disable plug-ins one by one
Sometimes the “Could not save password reset key” error may be caused by a plugin conflict. Disabling plug-ins one by one will help you identify which one may be causing the problem.
To do this, go to the WordPress admin panel and then to the “Plugins” tab. Disable each plugin one at a time, checking after each disabling to see if the password reset issue persists. If the problem disappears after disabling a certain plugin, you will know which plugin is to blame.
3. Update WordPress
If you are using an outdated version of WordPress, it may also cause various types of errors, including “Could not save password reset key”. It is always recommended to keep WordPress on the latest version to ensure security, stability and eliminate bugs.
4. Use the password reset plugin
One potential solution could be to use a password reset plugin. Plugins such as “WP Mail SMTP” or “Password Reset
You can also try the following steps to resolve this issue:
- Make sure that the plugin or theme is not causing the problem. Disable plugins and switch to the default theme to make sure they don't cause the error.
- Check your PHP settings and memory. Many times this error is caused by insufficient memory or bad PHP settings. You can increase the memory limit in the wp-config.php file by adding the following line of code:
define('WP_MEMORY_LIMIT', '256M');3. Contact your hosting. If the above steps don't help, please contact your hosting provider for assistance in resolving the issue.
If the issue is not resolved, it is recommended that you back up your site and update to the latest version of WordPress to rule out possible bugs in the older version of the software.
