An error message is displayed :
The query does not contain the correct number of placeholders (1) for the number of arguments passed (2). This message was added in version 4.8.3.
Problem: I am using Wordpress 4.3.22 .
Anybody has an explanation?
NB: that message is coming from wpdb::prepare
.
wpdb::prepare
. It's strictly hard-written "4.8.3" in the 4.3.22 version ofwp-db.php
.
