This thread is resolved. Here is a description of the problem and solution.
Problem:
The debug log is showing multiple notices indicating that the creation of dynamic property wpml_cms_nav_cache::$cache_to_option is deprecated.
Solution:
If you're experiencing this issue, we recommend deactivating the WPML CMS Nav plugin as it is not essential for the operation of WPML or String Translation.
Alternatively, you can set the debug mode to false to temporarily resolve the issue. To do this, add or modify the following code in your wp-config.php file:
define('WP_DEBUG', false);Please ensure to back up your site before making these changes.
If this solution does not apply to your case, or if it becomes outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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. If further assistance is needed, please open a new support ticket at WPML support forum.
