PHP Deprecated notice on Toolset Types after upgrading to PHP 8.3.x

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

Problem:
After upgrading to PHP 8.3.x, you are encountering a PHP Deprecation notice on Toolset Types 3.5.2. The notice indicates that the return type of OTGSToolsetCommonUtilsRecursiveDotFilterIterator::accept() should either be compatible with FilterIterator::accept(): bool, or the #[ReturnTypeWillChange] attribute should be used to temporarily suppress the notice.
Solution:
We recommend disabling the debug mode in WordPress to prevent these warnings from being displayed to your visitors. This can be achieved by editing your wp-config.php file and ensuring it includes the following line:

define('WP_DEBUG_DISPLAY', false);

Mihai Apetrei Supporter Languages: English (English ) Timezone: Europe/Bucharest (GMT+02:00)	Hi there, Thank you for contacting WPML support. PHP v8.2.x and up are relatively new versions and not yet fully compatible with WPML. However, I noticed that the error you're encountering is just a warning 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 ); Also, please take a look here in regards to deprecated errors in general showing up from PHP 8.2 and up: https://wpml.org/errata/php-8-2-deprecated-creation-of-dynamic-property-whip_requirementscheckerconfiguration-is-deprecated/ I hope that you will find all this information helpful.

Marco	Still not fixed. The WP_DEBUG thing is not a solution. Fixing the bug is.

Mihai Apetrei Supporter Languages: English (English ) Timezone: Europe/Bucharest (GMT+02:00)	Hi there. I understand your concern. Deprecation notices are not errors/bugs. Please take a look at the explanation from the official WordPress.org website (I will also assign a screenshot): 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 but for now, if you want to hide them from visitors, you can set that value to "false". I hope that you will find this information helpful.
