We have been trying to upload a new banner and it has not been loading. we get the following message: Warning: Missing argument 2 for wpdb::prepare(), called in /home/medall10/public_html/wp-content/plugins/polylang/include/core.php on line 474 and defined in /home/medall10/public_html/wp-includes/wp-db.php on line 992
Why is this happening and how can we fix this?
