Error message: Uncaught Error: [] operator not supported for strings in

Hi all,

I recently inherited a site with an old version of BeTheme (15.7) and it was migrated over to a new host with PHP 7.3, and all is working well except when I try and update any content (using Muffin Builder). When I change any content via Pages, and go to update the page, I get this error in the console:

WordPress version 5.3.2

Current theme: Betheme Child (version 1.6.1)
PHP version 7.3.11

An error of type E_ERROR was caused in line 82 of the file /home/umuw1a2et54m/public_html/ytnutrition/wp-content/plugins/query-monitor/collectors/php_errors.php.

I am using BeTheme 15.7 with Muffin Builder. It worked previously on PHP 5.6.

Can anyone assist? If I update to the latest version of the theme will it fix this issue? If I update to the latest version, will my site stay intact?

Thanks,
Leigh
