    Hi Tony,

    The error messages you’re seeing indicate that there is a problem with a callback function in WordPress, which is likely due to a plugin or theme conflict. Let’s go through the steps to resolve this issue.Step-by-Step Solution

    1. Deactivate Plugins:
      • Navigate to the wp-content directory.
      • Rename the plugins folder to something like plugins_backup. This will deactivate all plugins.
      • Try logging into your WordPress admin dashboard. If you can log in, one of the plugins is causing the issue.
      • Rename the plugins_backup folder back to plugins and then deactivate each plugin one by one through the admin dashboard to identify the problematic plugin.
    2. Switch to a Default Theme:
      • If deactivating plugins doesn’t resolve the issue, it could be a theme conflict.
      • Access the wp-content/themes directory.
      • Rename your active theme’s folder (e.g., your-theme to your-theme_backup).
      • This will force WordPress to revert to a default theme like Twenty Twenty-One.
      • Try logging in again to see if the issue is resolved.

    By following these steps, you should be able to identify and resolve the issue causing the errors on your website. If you need further assistance, please feel free to reach out.

    Best regards,
