This is the error I got I mean it works okay, but this happened when I was browsing on the backend. Not sure if I need to be concerned about this but just thought I should post it in case others got this.

I’m running php 8.1 and on the free version. I change the server and site info for security purposes.

WordPress version 6.5.2
Current plugin: Folders (version 3.0.2)
PHP version 8.1.28

First, visit your website (https://simplytheojames.com/) and check for any visible issues. Next, visit the page where the error was caught (https://simplytheojames.com/wp-admin/upload.php) and check for any visible issues.
