Problem: You are experiencing issues with widget editing and language differentiation on your WordPress site using the Cocoon theme. Specifically, when trying to edit, add, or delete widgets, the widget editing page breaks, displaying a PHP warning: 'Array to string conversion in wp-includes/taxonomy.php on line 4906'. This error prevents you from managing widgets and correctly setting up display conditions to separate Japanese content from English content. Solution: We recommend that you disable PHP warnings which are not affecting functionality but are visible due to your site's debug settings. Please add the following lines to your wp-config.php file to hide these warnings:
This should help in hiding the PHP warnings and allow you to manage your widgets without the page breaking.
