Prerequisites

  • I have searched for similar issues in both open and closed tickets and cannot find a duplicate.
  • The issue still exists against the latest stable version of Elementor.

Description

I was just hit with the following error on a production site:


>  Warning: Undefined array key "carousel_items" in ../wp-content/plugins/elementor-pro/base/base-carousel-trait.php on line 1385
>  Fatal error: Uncaught TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given in ../wp-content/plugins/elementor-pro/base/base-carousel-trait.php:1385

Cloned the site to Local, disabled everything and the error still persists. Using the 'Loop Carousel' element.

Rollback to 3.15.1 and 3.15.2 (pro) fixed the problem.

Steps to reproduce

This website hasn't been touched in months. The loop carousel element contains some very basic elements (image and text).

Isolating the problem

  • This bug happens with only Elementor plugin active (and Elementor Pro).
  • This bug happens with a Blank WordPress theme active (Hello theme).
  • I can reproduce this bug consistently following the steps above.

Same issue here.. I have rolled back to update version 3.15.1 for Elementor and Elementor Pro and regenerate CSS to resolve the problem.

This issue is a duplicate of: #23804

There is a new field in the widget to enter how many posts to show. If left blank it will show this "undefined aray" error. Update Elementor and then add a number. This is what resolved it for me.

An idea to fix this is for Elementor to force a default fallback number of 6 or 10.

PHP 8+ compounds the issue where elements do not load placed after the widget. PHP 7.4 shows the error but still loads widgets placed after it.

I can't even try your solution because this error breaks the editor too.
