Title: Getting "Warning: array_map(): Argument #2 should be in array Last modified: August 30, 2016 --- # Getting "Warning: array_map(): Argument #2 should be in array * Resolved [TMSpice](https://wordpress.org/support/users/tmspice/) * (@tmspice) * [10 years, 5 months ago](https://wordpress.org/support/topic/getting-warning-array_map-argument-2-should-be-in-array/) * I did my WordPress update yesterday and since then I’ve been getting Warning: array_map(): Argument #2 should be in array in home/lifeand17public_html/wp-includes/ category-templates.php on line 1158. * This appears on all posts when fully opened but not on my front page. * How do I resolve this, please? * And I’d like to add that since this appears to be a ‘mass’problem (I’ve read other topics on this since yesterday), can this be a problem of the new WordPress 4.4?

Is there a possibility of someone pin-pointing my actual problem and proffering a possible solution? * Thank you * Moderator [Marius L.

As James Huff pointed on [WordPress 4.4 Master List](https://wordpress.org/support/topic/read-this-first-wordpress-44-master-list?replies=6) a few hours ago, a patch for this problem has been made as Marius mentioned above: * [https://core.trac.wordpress.org/attachment/ticket/34723/34723.patch](https://core.trac.wordpress.org/attachment/ticket/34723/34723.patch) * To fix, open your category-template.php and replace lines 1144 – 1158… * ``` function get_the_terms( $post, $taxonomy ) { if ( ! $post = get_post( $post ) ) return false; $terms = get_object_term_cache( $post->ID, $taxonomy ); if ( false === $terms ) { $terms = wp_get_object_terms( $post->ID, $taxonomy ); $to_cache = array(); foreach ( $terms as $key => $term ) { $to_cache[ $key ] = $term->data; } wp_cache_add( $post->ID, $to_cache, $taxonomy . '_relationships' ); } $terms = array_map( 'get_term', $terms ); ``` * …with the new code from the patch: * ``` function get_the_terms( $post, $taxonomy ) { if ( ! $post = get_post( $post ) ) return false; $terms = get_object_term_cache( $post->ID, $taxonomy ); if ( false === $terms ) { $terms = wp_get_object_terms( $post->ID, $taxonomy ); if ( ! is_wp_error( $terms ) ) { $to_cache = array(); foreach ( $terms as $key => $term ) { $to_cache[ $key ] = $term->data; } wp_cache_add( $post->ID, $to_cache, $taxonomy . '_relationships' ); } } if ( ! is_wp_error( $terms ) ) { $terms = array_map( 'get_term', $terms ); } ``` * So is now line 1144 – 1162. This fix will be included in the future 4.4.1 I suppose * [guitavares](https://wordpress.org/support/users/guitavares/) * (@guitavares) * [10 years, 5 months ago](https://wordpress.org/support/topic/getting-warning-array_map-argument-2-should-be-in-array/#post-6833809) * Great, the patch above works just perfectly. * Thanks [@ronald](https://wordpress.org/support/users/ronald/).kubo! * [mikon82](https://wordpress.org/support/users/mikon82/) * (@mikon82) * [10 years, 5 months ago](https://wordpress.org/support/topic/getting-warning-array_map-argument-2-should-be-in-array/#post-6833863) * This patch does indeed work for our plugin, Foodpress, as well! thanks! * [freddeume](https://wordpress.org/support/users/freddeume/) * (@freddeume) * [10 years, 5 months ago](https://wordpress.org/support/topic/getting-warning-array_map-argument-2-should-be-in-array/#post-6833934) * I got the same problem with Event Manager. * But my function does not look exactly the same.

One of the sites I maintain is unfortunately a GoDaddy hosted WordPress install so you can’t edit any core files. * [TJ Kelly](https://wordpress.org/support/users/tjkelly/) * (@tjkelly) * [10 years, 5 months ago](https://wordpress.org/support/topic/getting-warning-array_map-argument-2-should-be-in-array/#post-6833964) * Also, when can we expect to see 4.4.1? * Moderator [Marius L.

This is the loophole to GoDaddy’s system: 1. Download the entire folder wp-includes to your local machine 2. Make the edit to category-template.php on your local machine (you should be able to edit the permissions locally 3. Via FTP, rename wp-includes on your server to something else (i.e. wp-includes- old) 4. Upload your local copy of wp-includes to your server 5. Flush the GoDaddy Cache 6. Enjoy your website sans error * This worked perfectly for me. * Moderator [Marius L.
