Wrong use of $wpdb->prepare
-
Causes the error “Missing argument 2 for wpdb::prepare() on line 159”.
Upon looking at the code at around that line it becomes obvious that the use of #wpdb->prepare is totally wrong there.
Was 4 years ago the documentation for $wpdb teaching to use it this weird way?
This plugin seems to be abandoned.
Don’t install unless it’s fixed or upgraded for the current state of WordPress.
