What version of PHP are using?
Only PHP 5.3 or later versions enables use of inline anonymous functions with array_map

this could be, as code works properly on my server - asked the user for verification if php 5.2 is used.
do you happen to know how to change this code to make it run on phone 5.2 too?

This is part of the following function (not written by me) which is used to detect where the shortcode to our plugin is used (posts, pages, CPT, widgets):
function lmm_get_map_shortcodes($id, $type){
global $wpdb;
$lmm_options = get_option( 'leafletmapsmarker_options' );
$shortcode = '[' . $lmm_options['shortcode'] . ' ' . $type . '="' . $id . '"';
$builtin_post_types = array('post', 'page');
$post_types = get_post_types(array('public' => true, '_builtin' => false));
$post_types = implode(',', array_map(function($post_type){ return "'" . esc_sql($post_type) . "'"; }, array_merge($builtin_post_types, $post_types)) );
$posts = $wpdb->get_results( $wpdb->prepare("SELECT ID,post_title FROM $wpdb->posts WHERE (post_type IN ($post_types) ) AND post_content LIKE %s ",'%'.$shortcode.'%') );
$result = '<ul style="margin:0;">';
foreach ($posts as $post) {
if ($post->post_title != NULL) { $post_title = $post->post_title; } else { $post_title = 'ID ' . $post->ID; }
$result .= '<li style="margin-bottom:0;clear:both;">' . ucfirst(get_post_type($post->ID)) . ': <a href="' . get_permalink($post->ID) . '" title="' . esc_attr__('view content','lmm') . '" target="_blank">' . $post_title . '</a>';
if(current_user_can('edit_others_posts')){
$result .= '<a style="float:right;" href="' . get_edit_post_link( $post->ID ) . '"> ('. __('edit','lmm') . ')</a>';
}
$result .= '</li>';
}
$widgets = get_option('widget_text');
if (!empty($widgets)):
foreach ($widgets as $w_key => $widget) {
$shortcode = '['.$lmm_options['shortcode'].' '.$type.'="'.$id.'"]';
if (is_array($widget)) {
if(isset($widget['text']) && $widget['text']!= ''){
if(strpos($shortcode, $widget['text']) !== FALSE) {
$result .= '<li style="margin-bottom:0;">';
$result .= sprintf(__('Found in a <a href="%1$s">widget</a>'), admin_url('widgets.php')) . '</a>';
$result .= '</li>';
}
}
}
}
endif;
$result .= '</ul>';
if ($result == '<ul style="margin:0;"></ul>') {
$result = __('not used in any content','lmm');
}
return $result;
