Parse error

[demotopia]

Hello

Probably during the last update of a plug-in I have this error:

Parse error: syntax error, unexpected '?' in /membri/demotopia/wp-content/plugins/cc-coming-soon/admin/includes/class-cc-coming-soon-preview.php on line 743

I don't have access to my backend, so I have no idea how to proceed.
The content of the site is not important, it is to be reviewed in its entirety. What interests me is to keep the domain.

How can I proceed? Thanks for everything
