Elementor not loading on Edit Page

Elementor is the one of the most popular Website Builder plugins in WordPress.

Sometimes, when we click on “Edit with Elementor” for any page, it is stuck on the loading screen. There are some of the common fixes mentioned in the Official Elementor guide. Most of these issues are related to a resource issue, a conflict with another plugin or theme, or a server configuration. Here, we have provided tips similar to the Elementor guide as well as some additional fixes.

Note: It is important to backup your WordPress website before performing these checks, so that you do not lose any data especially during theme/plugin activations.

Check PHP version & Memory Limit:

Elementor tools allows you to check if current PHP related configuration supports Elementor or not.

  • To check PHP requirement related issues, Go to: WordPress Dashboard > Elementor > System Info.

Update Elementor:

Go to Dashboard > Updates and click the Check Again button if there is (Elementor) plugin update

Switch Theme:

There are chances that currently activated theme has compatibility issue with Elementor plugin.

Site Health

Site Health can tell you if WordPress Ajax, REST API or other features are not working properly, therefore Elementor does not load. See, if you find any issue related to Loopback request or REST API, so that you can debug accordingly.

  • Go to: WordPress Dashboard > > Tools > Site Health to get a hint about the issue.

Deactivate other plugins:

There are high chances that some plugin is having conflict with Elementor. You need to deactivate other plugins to find where the issue is.

  • Deactivate all of your plugins except Elementor and Elementor Pro.

Re-install WordPress:

This is rare but sometimes WordPress is not installed properly after WordPress update.

  • If an issue occurred after WordPress update, you can try WordPress re-install to fix the issue.

These tips will help you to identify the issue related to Elementor loading. If there is any theme/plugin conflict, you need to stop using it or contact their developer.

In case, you find something in Site Health and System Info, you may need to take help from the Server/Hosting Team to meet the requirement.

Parent drop-down missing for hierarchical custom post type or Gutenberg

When we are creating 'hierarchical' custom post types, sometimes Page Attributes or Parent dropdown is missing. This is due to the required parameter missing in WordPress register_custom_post() function.

Common Issues:

  • 'Page Attributes' section is not visible in hierarchical custom post type (similar to page) editor
  • Parent drop-down missing in Gutenberg editor
  • Custom post type does not behaves like pages (parent/child relationship)


In register_custom_post() function, make sure in added 'page-attributes' in 'supports' and 'hierarchical' is set to true.

'supports'     => array('title', 'editor', 'author', 'thumbnail', 'page-attributes'),
'hierarchical' => true,

Additionally, in $labels arguments, if you have empty 'parent_item_colon', it cause an issue in Gutenberg and makes parent dropdown hidden. Therefore, either do not use this argument at all or mention some label string.

Complete Code to create hierarchical custom post type:

function cpt_news_function() {
	$labels = array(
		'name'               => _x( 'News', 'post type general name', 'textdomain'),
		'singular_name'      => _x( 'News', 'post type singular name', 'textdomain'),
		'add_new'            => _x( 'Add New', 'textdomain'),
		'add_new_item'       => __( 'Add New News', 'textdomain'),
		'edit_item'          => __( 'Edit News', 'textdomain'),
		'new_item'           => __( 'New News', 'textdomain'),
		'all_items'          => __( 'All News', 'textdomain'),
		'view_item'          => __( 'View News', 'textdomain'),
		'search_items'       => __( 'Search News', 'textdomain'),
		'not_found'          => __( 'No News found', 'textdomain'),
		'not_found_in_trash' => __( 'No News found in the Trash','textdomain'),
		'parent_item_colon'  => 'Parent',
		'menu_name'          => 'News'
	$args = array(
		'labels'        => $labels,
		'description'   => 'Holds our News and News specific data',
		'public'        => true,
		'menu_position' => 5,
		'publicly_queryable' => true,
		'query_var' => true,
		'rewrite' => array('slug' => 'news'),
		'supports'      => array('title', 'editor', 'author', 'thumbnail', 'page-attributes'),
		'hierarchical' => true,
		'has_archive'   => false,
		'show_in_rest'       => true,
		'menu order' => true
	register_post_type( 'my_news', $args );
add_action( 'init', 'cpt_news_function' );
