    im following this page : https://learn.www.ads-software.com/lesson/action-hooks/

    but when I put that code in the functions.php of the twentytwentyfour theme I see this error message:

    The function names in the various sample snippets are not consistent. “setup_theme” and “theme_setup” both occur. They must all be the same, one way or the other.

    TBH I’m not sure where you’d report this error in the training docs. I recommend asking in the Training Team’s Slack channel for specific direction. If you’ve not yet joined Slack, follow these instructions.
