This is not a PHP error, as you were calling it.
A PHP error looks like this: https://i.imgur.com/lqkAIXL.jpg
What you are looking at, is a “Controlled Warning” triggered by the Sucuri plugin after detecting that one or more of the files that power WordPress in your website has been modified or deleted. Unfortunately, it’s impossible to see the list of corrupt files from the screenshot you posted so I cannot help much at the moment.
You can scroll down the table and find some options to fix those files, you can either restore them (if they have been modified), mark them as fixed (if you think the warning is a false positive), or delete them (if they are not part of a normal WordPress installation).
Marking as resolved, let me know if you need more information.
