Problem: The client installed WPML and encountered compatibility issues with PHP 8.2, resulting in deprecated function notices flooding their logs. These notices, while not currently causing functional issues, are expected to lead to fatal errors in future PHP versions and are significantly increasing the size of log files. Solution: We recommend disabling the debug mode in WordPress to prevent these warnings from being displayed to visitors. This can be done by adding the following line to your wp-config.php file:
define('WP_DEBUG_DISPLAY', false);
For more details, please refer to the official WordPress documentation on PHP compatibility: WordPress and PHP 8.0-8.1. Additionally, a new version of the WPML Sticky Links plugin is being prepared to address these deprecation notices. Until this version is released, you can apply a temporary fix detailed here: WPML Sticky Links Deprecated Error on PHP 8.x.
Please note that the solution provided might be outdated or not applicable to your specific case. We highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket at WPML Support Forum.
