  • Ticket #64314 – Description

    initial v8  
    88The API request to save the post will fail, returning a 500 error. The PHP log will list say:
    99
    10   PHP Fatal error:  Uncaught TypeError: trim(): Argument #1 ($string) must be of type string, array given
     10  `PHP Fatal error:  Uncaught TypeError: trim(): Argument #1 ($string) must be of type string, array given`
    1111
    1212The cause of the error is the function `wp_save_post_revision`, at `wp-includes/revision.php`. At line 190 it uses `normalize_whitespace( $post->field )`, which only works with strings, however `$post->field` will be an array if the meta is an array  and that will cause the fatal error.
