من یکی از سایت هام رو به وردپرس جدید آپدیت کردم که باعث نابودی اون شد

هنگامی که میخوام به تنظیمات قالب وارد بشم تا اون رو ویرایش کنم با پیغام زیر مواجه میشم

Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, ‘P2_Options::صفحه’ was given in /home3/balyan/public_html/sms/wp-includes/plugin.php on line 470

نوشته : Alireza Xn

پوشه پلاگین ها رو تغییر نام بدید به احتمال زیاد یکی از پلاگین ها با نسخه جدید وردپرس فیکس نیستش .

نوشته : سیدرضا بازیار

از پلاگین ها نیست

یه فایل به نام plugin.php وجود داره که کار های عجیبی رو انجام میده و نمیشه اون رو ویرایش کرد

کد plugin.php :

* To hook methods, you’ll need to pass an array one of two ways.

/**

* Hooks a function or method to a specific filter action.

*

* WordPress offers filter hooks to allow plugins to modify

* various types of internal data at runtime.

*

* A plugin can modify data by binding a callback to a filter hook. When the filter

* is later applied, each bound callback is run in order of priority, and given

* the opportunity to modify a value by returning a new value.

*

* The following example shows how a callback function is bound to a filter hook.

* Note that $example is passed to the callback, (maybe) modified, then returned:

*

*

* function example_callback( $example ) {

* // Maybe modify $example in some way

* return $example;

* }

* add_filter( 'example_filter', 'example_callback' );

*

*

* Since WordPress 1.5.1, bound callbacks can take as many arguments as are

* passed as parameters in the corresponding apply_filters() call. The $accepted_args

* parameter allows for calling functions only when the number of args match.

*

* Note: the function will return true whether or not the callback

* is valid. It is up to you to take care. This is done for optimization purposes,

* so everything is as quick as possible.

*

* @global array $wp_filter A multidimensional array of all hooks and the callbacks hooked to them.

* @global array $merged_filters Tracks the tags that need to be merged for later. If the hook is added, it doesn’t need to run through that process.

*

* @since 0.71

*

* @param string $tag The name of the filter to hook the $function_to_add callback to.

* @param callback $function_to_add The callback to be run when the filter is applied.

* @param int $priority (optional) The order in which the functions associated with a particular action are executed. Lower numbers correspond with earlier execution, and functions with the same priority are executed in the order in which they were added to the action.

* Default 10.

* @param int $accepted_args (optional) The number of arguments the function accepts.

* Default 1.

* @return boolean true

* need to be added.
