[Resolved] PHP Deprecated: Creation of dynamic property WPML_LS_Menu_Item::$current is deprecated

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

Problem:
The client reported multiple PHP deprecation notices related to WPML after updating to PHP 8.2. These include deprecated property creation for WPML_LS_Menu_Item.
Solution:
We informed the client that these issues are already addressed in the upcoming WPML version 4.7, which is in the final QA stage. Meanwhile, we recommended a workaround involving a site backup and following the steps provided in a related support ticket: https://wpml.org/forums/topic/deprecated-errors-with-php-8-2/#post-15994511.

To prevent these warnings from displaying to site visitors, we advised disabling the debug mode in WordPress by adding 

define( 'WP_DEBUG_DISPLAY', false );

to the wp-config.php file. More details on this can be found here: https://wordpress.org/documentation/article/debugging-in-wordpress/.

If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, please open a new support ticket. 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.

The following notices are already fixed in the upcoming version of WPML(4.7). It is currently in the final QA stage.

Hi Bigul, i see I'm on php 8.2.22 and WPML is on version 4.6.12.. Maybe I'll wait until WPML 4.7?

Hello,

Thank you for the feedback. Yes, it happens with a conclift with PHP 8.2.* versions. But it will not cause any issues in the functionality of the plugin, just an alert. So kindly wait for the WPML 4.7 release. We will update you once it is ready.

Therefore to prevent unwanted warnings and errors from being displayed to your visitors, it's best to disable debug mode in WordPress. This is a recommended practice to ensure a smoother user experience. To do so, edit your wp-config.php file and add or modify the following line:

define( 'WP_DEBUG_DISPLAY', false );
