Warning: call_user_func_array() [function.call-user-func-array]

I have just uploaded a site to my server and I’m getting this error in relation to plugin.php

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘cp_admin_init’ was given in /…/html/…/wp-includes/plugin.php on line 395

Any clues as to what this means? Oddly enough, the same site runs just fine if I run it on my computer with MAMP.

Line 395 of plugin.php consists of:
```
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 );
```

I’m having this same problem and it’s driving me crazy. Anyone know?

Hi Kesh,

It turned out that the cause of this problem was a function call in my theme’s functions.php file. Check if you have this line in your theme’s functions.php:

add_action('init', 'cp_admin_init');

I’m not sure what it does but it came with the theme I was working with. Comment it out and see if it solves the problem. It worked for me.

Getting the same error after trying to create custom posts with changing functions.php. Using arras theme.
Everything works, but showing the mentioned error everywhere 🙁

I’ve just installed 3.2 and I’ve started getting the error ONLY on the ‘Widgets’ screen.

I don’t the add_action line of code (from ash.matadeen above) in my functions.php file.

I deactivated all plugins, and the error cleared.

Reactivated one at a time, and found the offending plugin. Informed the plugin author.

Thanks! Commented a certain line out and it worked.

My theme started giving this error after updating to WordPress 3.2.1, and the problem was not caused by a plugin I had installed (even though it mentions the plugin.php file in the error code)
