Elementor Pro Forms widget causing 500 error

Hi Support,

After adding a Mailchimp API key and adding an Elementor Form to the footer template (Porto theme) for newsletter subscriptions it will cause a 500 error on pages using that template (basically all pages) when opening to edit with Elementor.
