Hi there, I recently updated my site to PHP 8.2 and I get the following errors:
Deprecated: Creation of dynamic property Whip_RequirementsChecker::$configuration is deprecated in /var/www/html/wp-content/plugins/sitepress-multilingual-cms/vendor/yoast/whip/src/Whip_RequirementsChecker.php on line 37
Deprecated: Creation of dynamic property Whip_RequirementsChecker::$messageManager is deprecated in /var/www/html/wp-content/plugins/sitepress-multilingual-cms/vendor/yoast/whip/src/Whip_RequirementsChecker.php on line 38
As far as I see, it appears that your server is currently running on PHP v8.2.x, which is relatively new and not yet fully compatible with WPML. However, I noticed that the errors you're encountering on your homepage are just warnings regarding deprecated functions in WPML that will require modification in the near future. Nevertheless, these functions are still operational at present.
To avoid showing those unwanted warnings and errors to your visitors, it's best to disable the debug mode in WordPress. This is actually a recommended practice, so you won't have to worry about anything.
To achieve that, edit your wp-config.php file and make sure it has this line
define( 'WP_DEBUG_DISPLAY', false );

Also, I noticed that you are not using the latest version of WPML, I highly recommend updating them, and you could try disabling Yoast's Premium plugin as we got a similar issue related to it, let us know if that removes the error,
Thanks for the reply, PHP 8.2 was released on December 8, 2022, do you have any timeframe on official WPML support for 8.2?
The reason this has become a more pressing issue for us is that some hosts (specifically WP Engine) are force upgrading accounts to PHP 8.2.
Thanks,

From WP Engine:
Upgrade to PHP 8.2 now!
WP Engine’s PHP 8.0 will be reaching end of life on October 31. Prepare your websites for the PHP 8.2 upgrade to experience increased security and performance.
And:
Automatic PHP Upgrades
The EOL (End-Of-Life) process is a standard part of the release cycles of PHP (the open source programming language which powers WordPress). Once a version has reached “end of life”, PHP ceases to provide security support for it and it is no longer secure enough to remain on WP Engine servers.
For security purposes, WP Engine completely removes older versions of PHP from our servers once they have reached “end of life”. At this time, if your website is using an older version of PHP, it will be upgraded to a newer version automatically.
Our team will notify you via email several times before this automatic change occurs. We highly recommend updating as soon as possible when a new PHP version is released to ensure your site is receiving performance benefits as well as to ensure you can perform the upgrade in a suitable window for your needs. Automatic PHP upgrades cannot be deferred.
Also, the deprecated function that the error is calling will not affect the functionality of your website. So please ensure that no Fatal errors are logged instead.
In the meantime, I will escalate this matter to our developers, they should be aware of this,
