Fatal Error: Call to undefined function wp_get_current_user() in class-admin-men

    Hi there,

    I’m encountering a fatal error when activating Rank Math on one of my websites:

    Uncaught Error: Call to undefined function RankMath\Admin\wp_get_current_user()  
    in /wp-content/plugins/seo-by-rank-math/includes/admin/class-admin-menu.php:53

    It seems the function wp_get_current_user() is being called too early in the WordPress load sequence — before pluggable.php is loaded, where this function is defined.

    A temporary fix is to wrap the call like this:

    if ( ! function_exists( 'wp_get_current_user' ) ) {  
        require_once ABSPATH . 'wp-includes/pluggable.php';  
    }

    However, the best long-term solution would be to ensure this call runs only after WordPress has fully loaded the pluggable functions — ideally using the plugins_loaded or init hook.

    Please consider addressing this in a future update to prevent similar issues. Let me know if you need more details or access to the environment.

    Thanks for your support and for the great plugin!

    Hello @danieldumitruavram,
     
    Thank you so much for reaching out.
     
    Rank Math calls wp_get_current_user() inside the init hook (line 37), which runs after WordPress loads pluggable functions — so this error shouldn’t normally occur.
     
    It’s possible that another plugin or custom code is triggering things early. Could you please share the list of active plugins or any custom setup on the site? That will help us investigate further.
     
    Meanwhile, you can check first if the issue goes away when all plugins except Rank Math are disabled and the default theme is active. You may follow this troubleshooting guide so your users will not be affected: https://rankmath.com/kb/check-plugin-conflicts/
     
    Looking forward to your reply.

    I’m encountering the same fatal error again that I reported previously. The error message is:

    Uncaught Error: Call to undefined function RankMath\Admin\wp_get_current_user() in /wp-content/plugins/seo-by-rank-math/includes/admin/class-admin-menu.php:53

    After this happens, the site goes completely down, and the only way to temporarily fix it is by changing the PHP version from cPanel, which resets things and brings the site back online.

    Here’s what I’ve confirmed on my end:

    • I’m using the latest version of WordPress and Rank Math.
    • I’ve added the correct debug configuration in wp-config.php, but the fatal error doesn’t get logged in wp-content/debug.log — probably because it occurs too early in the execution.
    • Based on your previous answer, I understand this function is only called inside the init hook, which should be safe. However, the issue still happens, indicating something (perhaps a plugin or custom code) is triggering execution too early and causing Rank Math to load before pluggable.php is available.

    I’d really appreciate it if you could:

    1. Confirm if there’s any known fix or update for this issue.
    2. Suggest a way to prevent Rank Math from loading until wp_get_current_user() is guaranteed to be available, or at least gracefully fail instead of throwing a fatal error.

    Thanks in advance

    Hello @danieldumitruavram,

    Thank you for sharing the details.

    This shouldn’t happen because we do call the function inside the init hook which should throw an error but it seems that something in particular on your website is delaying some code execution which causes this function to not be available when we try to call it.

    To have this issue sorted, please get in touch with our development team using the following email address: [email protected]

    Looking forward to helping you.
