This is on a wp.com website, and it turns out the plugin I was trying to use to enable debugging wasn’t working right. I enabled SFTP access and made the necessary changes. This is the error message I am receiving.
[24-Nov-2024 21:51:48 UTC] PHP Fatal error: Uncaught Error: The script tried to modify a property on an incomplete object. Please ensure that the class definition "stdClass" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide an autoloader to load the class definition in /wordpress/core/6.7.1/wp-includes/formatting.php:5122
