WPML CMS Navigation 1.5.5

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're receiving deprecation warnings like 'Creation of dynamic property wpml_cms_nav_cache::$cache_to_option is deprecated' in your WordPress site using WPML CMS Nav plugin, this might be due to a conflict with PHP versions 8.3 and 8.2.
Solution:
We recommend setting the debug mode to false to temporarily resolve this issue. You can do this by adding or modifying the following line in your wp-config.php file:

define('WP_DEBUG', false);

Please ensure to back up your site before making this change. This workaround will suppress the warnings until a permanent fix is released in future updates of the WPML CMS Nav plugin.

If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. Should you need further assistance, please open a new support ticket at WPML support forum.

Bigul	Hello, Welcome to the WPML support forum. I will do my best to help you to resolve the issue. This has already been escalated to our developers and will be fixed in the future version of WPML CMS Nav. This notification happens because of a conflict with the PHP 8.3 and 8.2 versions. This alert won't affect the normal functioning of your site. As a temporary workaround, we recommend setting debug mode to false by adding or changing the following code in your wp-config.php file, located at the root of your WordPress installation: define('WP_DEBUG', false); This should help to resolve the issue until a permanent solution is implemented in future releases. Please try it after a site backup and let us know your feedback. -- Thanks! Bigul

The warnings are harmless to your site. You can continue using the workaround suggested earlier. If you're not utilizing the features of the WPML CMS Nav plugin, you might consider deactivating it.
