wp_insert_posts Fatal error: Maximum function nesting level of ‘100’ reached, aborting!
Fixed the problem I’ve added this line before the insertion of the posts. remove_action(‘save_post’, __FUNCTION__); final code: add_action(‘save_post’, ‘save_post_func’); function save_post_func(){ remove_action(‘save_post’, __FUNCTION__); include_once(ABSPATH . WPINC . ‘/feed.php’); $rss = fetch_feed($url); if (!is_wp_error($rss)) { $maxitems = $rss->get_item_quantity(5); $rss_items = $rss->get_items(0, $maxitems); foreach ($rss_items as $item) { wp_insert_post(array(‘post_title’ => ‘a’)); } } }
