WPML 4.7 Conflict with Plugins Using PSR/Log 3.0 Causes Fatal Error in WP-CLI

Open

Reported for: WPML Multilingual CMS 4.7.0

Topic Tags: Bug

Overview of the issue

WPML 4.7 has a compatibility issue with plugins that use PSR/Log 3.0, such as Rollbar. When WPML and Rollbar are both active, running WP-CLI commands (e.g., wp --info) triggers a fatal error due to method signature mismatches in the DebugFileLogger class.

PHP Fatal error:  Declaration of WPML\\PHP\\Logger\\DebugFileLogger::log($level, $message, array $context = []) must be compatible with Psr\\Log\\AbstractLogger::log($level, Stringable|string $message, array $context = []): void in ...\\wp-content\\plugins\\sitepress-multilingual-cms\\vendor\\wpml\\wpml\\lib\\Php\\Logger\\DebugFileLogger.php on line 8

  2. This worked for me:

    namespace WPML\PHP\Logger;

    class DebugFileLogger extends \Psr\Log\AbstractLogger {

    public function log( $level, $message, array $context = array() ) : void {
    if ( ! defined( 'WP_DEBUG' ) || ! WP_DEBUG ) {
    return;
    }

    $log = date( 'Y-m-d H:i:s' ) . ' [' . $level . '] ' . $message . PHP_EOL;
    \error_log( $log );
    }

    }
