Hi Steve,

Thank you for your response.

Yes, I have logged a ticket with them regarding this issue and they have found a fix. Apparently Piklist was modifying the $post_states array and turning it into a NULL variable and they weren’t checking it, before trying to iterate through it to add their own status to pages, which was causing a fatal crash. Now they’ve implemented a fix, the issue is gone.

If anyone is experiencing this issue, and wants to fix it before they will include this bug fix into their official release, you need to modify this file /wp-content/themes/Divi/includes/builder/feature/BlockEditorIntegration.php. You need to find function display_post_states (right it’s starting on line 288) and replace all of it with:

	/**
	 * Add 'Divi' to post states when builder is enabled for it.
	 *
	 * @param array $post_states Existing post states.
	 * @param object $post Current post object.
	 *
	 * @return array
	 */
	public function display_post_states( $post_states, $post ) {
		// Make sure that $post_states is an array. Third party plugin might modify $post_states and makes it null
		// which create various issue (i.e. Piklist + Having a page configured as a static page)
		if ( ! is_array( $post_states ) ) {
			$post_states = array();
		}	    
	    
		if ( et_pb_is_pagebuilder_used( $post->ID ) ) {
			// Remove Gutenberg if existing
			$key = array_search( 'Gutenberg', $post_states );
			if ( false !== $key ) {
				unset( $post_states[ $key ] );
			}
			// GB devs didn't allow this to be translated so why should we ?
			$post_states[] = 'Divi';
		}

		return $post_states;
	}

However, I think there is still a general issue with Piklist. Why is it modifying the $post_states array and making it NULL? I do not believe that’s an intentional behaviour. So what ends up happening is that Piklist strips all post statuses from pages, which I am pretty sure is a bug. For example, Piklist will cause the “Front Page” post state to not display on the All Pages section in WP Dashboard.
