Fatal Error after update 2.7.5

Hi there,

I have updated Elementor to 2.7.5 and also WordPress to 5.3. I am running the OceanWP theme and only Formidable Forms and Wordfence pretty much on the site.

However I’m getting this error when I try to edit a page?

Catchable fatal error: Argument 1 passed to Elementor\Controls_Stack::sanitize_settings() must be of the type array, null given, called in /home/greencar/public_html/wp-content/plugins/elementor/includes/base/controls-stack.php on line 1022 and defined in /home/greencar/public_html/wp-content/plugins/elementor/includes/base/controls-stack.php on line 1912

I then tried to update my PHP version to 7.0 and then I’m getting the following error:

Uncaught TypeError: Argument 1 passed to Elementor\Controls_Stack::sanitize_settings() must be of the type array, null given, called in /home/greencar/public_html/wp-content/plugins/elementor/includes/base/controls-stack.php on line 1022 and defined in /home/greencar/public_html/wp-content/plugins/elementor/includes/base/controls-stack.php:1912

What does this mean and how do I correct it so I can edit pages again please?

Thank you in advance.
