PHP fatal error in posts.php

  • Hi, getting a lot of these errors on my production install. It seems to be an issue with WP core. Has anyone seen this before, and is there a way to fix it? Thanks

    This problem may be a plugin or theme conflict. Please attempt to deactivate all plugins and switch to the default Twenty Twenty-Four theme. If the problem goes away, re-activate them one by one to identify the source of the problem.

    If you can install plugins, install Health Check. On the troubleshooting tab, you can click the button to deactivate all plugins and change the theme for you while you’re still logged in without affecting normal visitors to your site.
