    Hey! That warning is pretty common after a WordPress update. Basically, some old files didn’t get removed automatically. The Core.php file you mentioned is leftover from the previous version.

    Here’s what I’d do:

    1. Backup everything first – your site files and database. Just in case.
    2. Check the file – it’s safe to delete if it’s not part of the current WordPress version.
    3. Delete it – you can use your hosting file manager or FTP to remove wp-includes/SimplePie/src/Core.php.
    4. Test your site – make sure everything still works after deleting it.

    If you’ve got a backup, there’s very little risk. Your site should run fine once the old file is gone.

    This is a known bug in version 6.9. There is also a ticket from the developers here: https://core.trac.wordpress.org/ticket/64336 – I think this will be fixed in version 6.9.1. Just leave the file where it is and ignore any warnings that anyone gives you about it. It’s not a big deal.

    hI threadi,

    Thanks for your advice. I’ll leave it.

    Unfortunately I have >40 websites therefore there would be lot of warnings received.

    No, it’s a file that isn’t being used.
