 * I modified my theme metabox.php to fit my needs but i get this error when i go
   to add a new listing :
 * > Warning: call_user_func_array() expects parameter 1 to be a valid callback,
   > function ‘mytheme_add_box’ not found or invalid function name in E:\xampp\htdocs\
   > wordpress\wp-includes\plugin.php on line 406
 * I have a online version of this wordpress site but it is not modified if it helps
   this is the website [http://www.dreamsimob.ro](http://www.dreamsimob.ro)
 * this is the old code

 * That’s not a theme that’s supported here, only themes downloaded from the [WordPress repo](http://wordpress.org/themes/)
   are.
 * That said, you should back out your changes (obviously 😉 ) and then create a
   child theme of that Avenue theme.
 * [http://codex.wordpress.org/Child_Themes](http://codex.wordpress.org/Child_Themes)
 * Activate that child theme and try your modifications on that child theme instead.
   It’s safer that way.
 * Whatever you do, do not copy the parent theme’s `functions.php` file into the
   child theme directory. That just won’t work. Whatever changes you wanted to make
   usually they can be made by editing copies of the theme files such as `header.
   php` or `footer.php`.
 * For more specific help then consider contacting the theme author.
