[Resolved] Nav menus are not showing when WPML is active

Problem:
The client reported that the navigation items in the header and footer were not displaying when WPML was active, despite previously functioning correctly. The issue persisted even after deactivating other plugins and reverting to a default WordPress theme.

Solution:
1. **Increase WordPress Memory Limit:**
* Access your website's files via FTP or your hosting control panel's file manager.
* Locate the

wp-config.php

file in the root directory of your WordPress installation.
* Open the

wp-config.php

file for editing.
* Add the following line just before the

/* That's all, stop editing! Happy publishing. */

line:

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

* Save the changes to the

wp-config.php

file.

2. **Re-synchronize Menus:**
* Go to WPML → WP Menus Sync.
* Click the Sync button.
* Review the changes, select any menu items that need to be synchronized, and click Apply changes.

If these steps do not resolve the issue, it may be due to a conflict with other plugins or the server environment. In such cases, we recommend disabling the WP Performance MU plugin as it was found to resolve the issue in this instance.
