PHP Notice on WordPress Widgets screen with Elementor ‘Nested Elements’ active

Hi there,

Thanks for contacting us and hope you are doing well and having a great day.

To rule out the possibility of a plugin or theme conflict, please deactivate all your plugins (besides Elementor ). If it solves the issue reactivate them one by one to find the culprit. If it didn’t help, switch your theme (temporarily) to a default WP theme such as Twenty Nineteen and see if it makes any difference.

Also, this could happen due to our Elementor performance experiments you can try to deactivate them. To deactivate them you can go to Elementor > settings > features

Performance features currently in the experimental stage are:

• Element Caching – Elements caching reduces loading times by serving up a copy of an element instead of rendering it fresh every time the page is loaded. When active, Elementor will determine which elements can benefit from static loading – but you can override this.
• Inline Font Icons – This experiment renders icons as SVGs without loading the Font-Awesome and eicons libraries. Since SVGs are vector-based images which are rendered using the browser’s engine, they do not increase server requests which improves performance

I am looking forward to hearing back from you soon.

Kind regards,
