在数据库YII中找不到活动记录类“Users”的表“users”

Question

i have tried to call a function (getMenu()) in CommonFunction.php (location : components/CommonFunction.php) , which will return some user data, but when i transferred my application from godaddy (shared hosting) to resellerclub (shared hosting) , following error showing.

The table "users" for active record class "Users" cannot be found in the database

1. table exists in database
2. letter case for file and class name for model checked
3. using the correct db connection
4. created a function (say abc()) in CommonFunctions.php which is successfully fetching user information.
5. when tried to call above mentioned abc() from getMenu() , it again showing above error
6. am able to call the getMenu function from my other controllers but there is not issue for that
7. But when i tried to call getMenu from this specific function it is showing error
8. If assigned a static value to first fetching, it will show error for the next fetching in the same function .

commonFunction.php

   public static function GetMenu($user_id = 0) {

    $user_info = Users::model()->findByPk($user_id);
    if (!isset($user_info) || count($user_info) < 1)
        return;
    $user_profile = UserProfile::model()->find('user_id=:user_id', array(':user_id' => $user_id));
    $creteria = new CDbCriteria();
    $creteria->condition = "contributor=\"$user_info->user_name\"";
    $photo_upload_count = Godown::model()->count($creteria);

    $creteria = new CDbCriteria();
    $creteria->condition = "user_email=\"$user_info->email\"";
    $photo_purchase_count = Downloads::model()->count($creteria);

    //echo $photo_purchase_count; exit;
    $creteria = new CDbCriteria();
    $creteria->condition = "contributor_user_name=\"$user_info->user_name\"";
    $photo_sale_count = Downloads::model()->count($creteria);
    //echo $photo_sale_count; exit;

    $base = Yii::app()->getBaseUrl(true);
    $profile_pic_org = false;
    $profile_dummy = "$base/images/profile-img.jpg";
    if (isset($user_profile->profile_pic) && $user_profile->profile_pic != '') {
        $profile_pic_url = "$base/profile-pic/thumb/" . $user_profile->profile_pic;
        $profile_pic_org = "$base/profile-pic/" . $user_profile->profile_pic;
    } else {
        $profile_pic_url = "$base/images/profile-img.jpg";
        $profile_pic_org = "$base/images/profile-img.jpg";
    }
    if (isset($user_profile) && count($user_profile) > 0) { // profile for the user is almost complete , we can fetch that info too;
        $name = $user_profile->first_name . ' ' . $user_profile->last_name;
    } else {
        $a=explode('@', $user_info->email);
        $name = reset($a);
    }
    if ($user_info->user_type == 'c') { // find the statics if and only if the user is a contributor
        $creteria = new CDbCriteria();
        $creteria->condition = "contributor=\"$user_info->user_name\" and display_status =\"\"";
        $photo_pending_approval_count = Godown::model()->count($creteria);

        $creteria = new CDbCriteria();
        $creteria->condition = "contributor=\"$user_info->user_name\" and display_status =\"N\"";
        $photo_rejected_count = Godown::model()->count($creteria);

        $creteria = new CDbCriteria();
        $creteria->condition = "contributor=\"$user_info->user_name\" and display_status =\"Y\"";
        $photo_accepted_count = Godown::model()->count($creteria);
        $folder = self::GetUploadFolder($user_id);
        $folder = $folder['orginal'];
        $penging_file_count = 0;
        //echo $folder; exit;

    }
