Hi,
as I wrote, when the plugin is turned off the search works, after switching on it does not work … :
Warning: mysqli_query (): MySQL server has gone away in /var/www/dev.youtab.pl/wp-includes/wp-db.php on line 2030
Warning: mysqli_query (): Error reading result set’s header in /var/www/dev.youtab.pl/wp-includes/wp-db.php on line 2030
Warning: mysqli_real_connect (): (HY000 / 2002): Connection refused in /var/www/dev.youtab.pl/wp-includes/wp-db.php on line 1633
Connection refused
An error occurred while reconnecting to the database
This means that we have lost connection to the database on the localhost server. It is possible that the database server has stopped working.
Is the database server up?
Is the database server currently extremely overloaded?
If you are not sure what these phrases mean, probably contact your hosting provider. If you still need help, visit the WordPress Help Forum.
Notice: The wpdb function was called incorrectly. wpdb must have a database connection set up to use escaping. Learn more: Debugging in WordPress. (This message was added in version 3.6.0.) In /var/www/dev.youtab.pl/wp-includes/functions.php on line 4986
