    The error message is explicit : you are using the function theme_404_content in the file 404.php (line 25) of your theme, and this function does not exist.

    Take a look at the file functions.php of your theme, the function theme_404_content should be defined here.

    This error is in your theme and has nothing to do with wp lockdown.
