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. * [edwinkort](https://wordpress.org/support/users/edwinkort/) * (@edwinkort) * [15 years, 2 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array/#post-1774905) * 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 🙁 * [AndyiBM](https://wordpress.org/support/users/andyibm/) * (@andyibm) * [14 years, 11 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array/#post-1774919) * 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. * [corizzo](https://wordpress.org/support/users/corizzo/) * (@corizzo) * [14 years, 11 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array/#post-1774920) * AndyiBM- which plugin? * [AndyiBM](https://wordpress.org/support/users/andyibm/) * (@andyibm) * [14 years, 11 months ago](https://wordpress.org/support/topic/warning-call_user_func_array-functioncall-user-func-array/#post-1774921) * hey Corizzo, It’s the WYSIWYG Widget.
