An example is [this page](https://www.ironmanager.academy/?post_type=guide&s=glutei) where get_query_var returns an array as a result: * ```wp-block-code ["guide"]=> string(5) "guide" ``` * The solution indicated by [@tresorama](https://wordpress.org/support/users/tresorama/) was only partially correct (the array also uses the custom post type slug as an index and does not use a numeric value). To resolve the warning you need to add the following code before line 606: * ```wp-block-code if ( is_array($post_type) ) $post_type = reset( $post_type ); ``` * which extracts the custom post type slug.
