[Resolved] "Deprecated" errors with PHP 8.2

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

Problem:
After updating the site to PHP 8.2, deprecation errors appeared on the front end related to dynamic properties in WPML_LS_Menu_Item.
Solution:
If you're experiencing similar issues, we recommend disabling the debug mode in WordPress to prevent these warnings from appearing to your visitors. You can do this by editing your wp-config.php file and ensuring it includes the following line:

define('WP_DEBUG_DISPLAY', false);

Hi there.


In regards to the deprecated notices, these PHP versions are relatively new versions and not yet fully compatible with WPML.

However, I noticed that the messages showing up in the log are just warnings about deprecated functions that will require modification soon.

Nevertheless, these functions are still operational.

To avoid showing your visitors unwanted warnings and errors, it's best to disable the debug mode in WordPress. This is actually a recommended practice, so you won't have to worry.

To achieve that, edit your wp-config.php file and make sure it has this line

define( 'WP_DEBUG_DISPLAY', false );

Please take a look here in regards to deprecated errors in general:
https://wpml.org/errata/php-8-2-deprecated-creation-of-dynamic-property-whip_requirementscheckerconfiguration-is-deprecated/

Please also take a look at the explanation from the official WordPress.org website:
https://make.wordpress.org/core/2022/01/10/wordpress-5-9-and-php-8-0-8-1/

These notices will go away in future updates (as you mentioned, we took care of some of them but there are still others) but for now, if you want to hide them from visitors, you can set that value to "false".

I hope that you will find all this information helpful.
