you’re not alone. This happens when a plugin or theme loads translation files too early, before WordPress is fully ready.
This blog explains the causes and gives you simple, intermediate, and advanced fixes.

Actual error encountered:


Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the media-library-organizer domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information. (This message was added in version 6.7.0.) in /home/private/public_html/wp-includes/functions.php on line 6121

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the robo-gallery domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the google-analytics-for-wordpress domain was triggered too early. This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Why This Error Happens

  • WordPress expects translations to load after the init hook.
  • Some plugins/themes still load them immediately when PHP starts.
  • Since WordPress 6.7, doing it too early now triggers warnings to developers and users.

Solution Options

1. Patch via Mini Plugin (Simple Fix)

Create a file:
/wp-content/mu-plugins/fix-translations.php

<?php
add_action('init', function() {
    load_plugin_textdomain('plugin-domain', false, 'plugin-folder/languages/');
});
  • Easy to apply
  • May not fix everything if the plugin already loaded translations early

2. Override Load Textdomain (Advanced Fix)

Create a stronger control by delaying translations:

<?php
add_filter('override_load_textdomain', function($override, $domain, $mofile) {
    $domains = ['plugin-domain1', 'plugin-domain2']; // Add more domains
    if (in_array($domain, $domains, true)) {
        add_action('init', function() use ($domain) {
            load_textdomain($domain, WP_LANG_DIR . "/plugins/$domain-" . determine_locale() . ".mo");
        }, 1);
        return true;
    }
    return false;
}, 10, 3);
  • Complete fix
  • Future plugin updates won’t break

3. Hide Errors on Production (Optional)

If you only see the notice in production and it doesn’t break anything, you can hide notices safely:

define('WP_DEBUG', false);
define('WP_DEBUG_DISPLAY', false);
@ini_set('display_errors', 0);
  • Clean frontend
  • Error still exists (just hidden)

Best Practices

  • Always update plugins/themes when patches become available.
  • Notify plugin developers about this early loading issue.
  • Monitor the WordPress changelog to adapt your site for future updates.
