Something went wrong updating cyber panel

I attempted to update the Cyber panel to version 2.5. Now, I cannot see my websites. I got this error: “Error: Reverse for ‘OneClickBackups’ not found. ‘OneClickBackups’ is not a valid view function or pattern name.”

my website is: TheStylishStray.com

Since I cannot access cyber panel, I do not have the version information.

I believe the server is Ubuntu.
