The WordPress 6.7 update introduced a series of changes aimed at improving performance and debugging capabilities. However, many users, especially those managing WooCommerce shops with custom plugins and translation tools, have reported significant issues. This guide explores the problems, potential solutions, and frequently asked questions to help you restore functionality.

​Reported Problems

1. PHP Notices in Logs

Example:

[22-Nov-2024 08:24:17 UTC] PHP Notice: Function _load_textdomain_just_in_time was called incorrectly. Translation loading for the woocommerce-payments domain was triggered too early.

This error suggests that some plugins are attempting to load translations prematurely, violating the new debugging standards introduced in WordPress 6.7.0.

2. Admin Panel Issues

• 500 Internal Server Errors appearing on various pages.
• JavaScript errors in the browser console, such as:
  
  

Uncaught TypeError: Cannot read properties of undefined (reading 'unstable_scheduleCallback') at react-dom.min.js

These errors often result from outdated or conflicting scripts in plugins or themes.

3. Payment and Plugin Problems

Reports include:

• Partial payment failures in WooCommerce.
• Compatibility issues with plugins like Astra Add-On and others.

Solutions

1. Fix PHP Notices

Update the plugin or theme causing the notice. Ensure translation files are loaded at the appropriate stage, such as during the init action:

add_action('init', function() {    load_plugin_textdomain('woocommerce-payments', false, dirname(plugin_basename(__FILE__)) . '/languages');});

2. Fix Admin Panel and JavaScript Errors

• Update WordPress, themes, and plugins to the latest versions.
• Clear server and browser caches (e.g., Cloudflare cache and local cache).
• Temporarily deactivate plugins one at a time to identify conflicts.

3. Fix Payment Issues

• Disable any plugins conflicting with WooCommerce Payments.
• Check for plugin updates or contact the developers for assistance.

4. Verify Server Configuration

Ensure the server meets these minimum requirements:

• PHP version 8.0 or higher.
• Increased memory limits:
  
  

define('WP_MEMORY_LIMIT', '256M');define('WP_MAX_MEMORY_LIMIT', '512M');
