Overview of the issue

If you are using The Events Calendar plugin and its Integrate events in main blog loop feature, you will encounter that the root page appears blank when any parameter is added to the URL (example.com?foo=bar). This issue occurs specifically when WPML’s Use directory for default language setting is also enabled.

Workaround

Please, make sure of having a full site backup of your site before proceeding.

  • Open …/wp-content/plugins/the-events-calendar/src/Tribe/Query.php file.
  • Look for line 577.
  • Replace:
    	protected static function add_post_type_to_query( WP_Query $query, string ...$post_types ): void {
    		
    		$query_post_types = self::get_query_post_types( $query );
    
    		$updated_post_types = array_unique( array_merge( $post_types, $query_post_types ) );
    
    		$query->set( 'post_type', $updated_post_types );
    		$query->query['post_type'] = $updated_post_types;
    	}
    
  • With:
    	protected static function add_post_type_to_query( WP_Query $query, string ...$post_types ): void {
    		
    		$query_post_types = self::get_query_post_types( $query );
    
    		// WPML Workaround for compsupp-7426
    		if ( class_exists('Sitepress') ) {
    			$is_root_enabled = apply_filters( 'wpml_sub_setting', false, 'urls', 'directory_for_default_language' );
    			
    			if ( $is_root_enabled && is_home() ) {
    				return;
    			}
    		}
    
    		$updated_post_types = array_unique( array_merge( $post_types, $query_post_types ) );
    
    		$query->set( 'post_type', $updated_post_types );
    		$query->query['post_type'] = $updated_post_types;
    	}
