* The website I am working on got completely deleted and then we uploaded a back
up then we have had these function errors. Suggestion how to fix?
* Here are the errors:
* > Warning: call_user_func_array() expects parameter 1 to be a valid callback,
> function ‘do_css’ not found or invalid function name in /home/fresheye/public_html/
> rentlucky.com/wp-includes/plugin.php on line 470
> Warning: call_user_func_array() expects parameter 1 to be a valid callback,
> function ‘do_jslibs’ not found or invalid function name in /home/fresheye/public_html/
> rentlucky.com/wp-includes/plugin.php on line 470
* Here is the line it refers to:
* `* @return null Will return null if $tag does not exist in $wp_filter array`
* Here is the whole section:
* ```
/**
* Execute functions hooked on a specific action hook, specifying arguments in an array.
*
* @see do_action() This function is identical, but the arguments passed to the
* functions hooked to $tag are supplied using an array.
*
* @package WordPress
* @subpackage Plugin
* @since 2.1
* @global array $wp_filter Stores all of the filters
* @global array $wp_actions Increments the amount of times action was triggered.
*
* @param string $tag The name of the action to be executed.
* @param array $args The arguments supplied to the functions hooked to $tag
* @return null Will return null if $tag does not exist in $wp_filter array
*/
function do_action_ref_array($tag, $args) {
global $wp_filter, $wp_actions, $merged_filters, $wp_current_filter;
if ( ! isset($wp_actions[$tag]) )
$wp_actions[$tag] = 1;
else
++$wp_actions[$tag];
// Do 'all' actions first
if ( isset($wp_filter['all']) ) {
$wp_current_filter[] = $tag;
$all_args = func_get_args();
_wp_call_all_hook($all_args);
}
if ( !isset($wp_filter[$tag]) ) {
if ( isset($wp_filter['all']) )
array_pop($wp_current_filter);
return;
}
if ( !isset($wp_filter['all']) )
$wp_current_filter[] = $tag;
// Sort
if ( !isset( $merged_filters[ $tag ] ) ) {
ksort($wp_filter[$tag]);
$merged_filters[ $tag ] = true;
}
reset( $wp_filter[ $tag ] );
do {
foreach( (array) current($wp_filter[$tag]) as $the_ )
if ( !is_null($the_['function']) )
call_user_func_array($the_['function'], array_slice($args, 0, (int) $the_['accepted_args']));
} while ( next($wp_filter[$tag]) !== false );
array_pop($wp_current_filter);
}

* More than likely the file containing the declarations for `do_css()` and `do_jslibs()`
is not getting included or required for some reason.

* How do I find that file and how do I fix it?

* Use `grep` or similar (anything that does a full text search in all files and
recurses into sub-directories) to search for `function do_css` in _wp-content_.
Same for `function do_jslibs()`. How to fix it is harder to say. The file needs
to be included or required through any chain of similar references from the main
code file, _functions.php_ for themes and whatever file has the plugin header
for plugins.
* If it’s not code you have anything to do with, you should probably contact the
theme or plugin author responsible.

* I finally figured it out. Turns out it was related to the plugin tinyMCE Advanced
and I just needed to add the following code to my functions.php file. I added
it to the bottom of the file just before the closing tag.
* ```
//css and jslibs
function do_css()
{
wp_enqueue_style('thickbox');
}
function do_jslibs()
{
wp_enqueue_script('editor');
wp_enqueue_script('thickbox');
add_action( 'admin_head', 'wp_tiny_mce' );
}
add_action('admin_print_scripts', 'do_jslibs' );
add_action('admin_print_styles', 'do_css' );
```
* Just adding the solution just in case someone else ends up with the same error.

* How did you figure out which plugin was causing the trouble? I’m getting the
same error, but am not using that plugin.

* [@webdi](https://wordpress.org/support/users/webdi/) A lot of searching and reading
and trial and error. I tried a number of things and this was the only solution
that worked.

* Hmm, I’ve disable each plugin one at a time and still get the error. So it doesn’t
seem to be a plugin in my case.

and it did not work.

* [@pinkchick](https://wordpress.org/support/users/pinkchick/) have you tried disabling
the plugins one at a time?
* You have a similar problem but you need to determine first what plugin is causing
the problem.
