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If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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.
