• I am getting below error when try to save modified data for author/user on my blog.

    Warning: call_user_func_array() expects parameter 1 to be a valid callback, invalid function name in /wp-includes/plugin.php on line 496

    Warning: Cannot modify header information – headers already sent by (output started at /wp-includes/plugin.php:496) in /wp-includes/pluggable.php on line 1196

    I read multiple posts in WP forum which have been closed. But it couldn’t help me to fix this.

    Anyone?

    Thanks.

  • The 2nd error you are seeing is caused by the first error. The first error appears that you have setup a hook or filter but provided an invalid function to run on that hook or filter.

    Is it possible to see the example code?

    Hi Chris,

    Thanks for quick response.

    I have not setup any hook or filter. Can you please tell me from which file do you need code?
