Serious Error

Hi everyone, I’m looking for some help. My site had been working fine, up until last night when I received an automated email from WordPress stating an error had occurred.

This error is now showing in the plugin section:
An error of type?E_ERROR?was caused in line?26?of the file?/homepages/27/d4297837148/htdocs/wordpress/wp-content/plugins/elementor/modules/promotions/module.php.

Unfortunately, I am not overly savvy on WordPress, but I have tried the following:
Uninstalled and reinstalled Elementor
Reverted back to a different version of Elementor

I am not sure what has changed as automatic updates are currently turned off, the website is now showing as offline and will either show a blank screen, or show as an Internal Server Error.

Anyone any ideas? Thanks so much!
