EOAuthUserIdentity getting error on getting token - php

Question

I am using jorgebg/yii-eoauth library. I use the library with Yii EAuth extension. By requirements yii eauth
Requirements
Yii 1.1 or above
PHP curl extension
loid extension
EOAuth extension
Well, I come across with this problem. I checked it in local with linkedin account (no social accounts work on local server, except linkedin ) and it works perfectly. But login system doesn't work on server. Can you help me in this case ? Thanks in advance !
I didn't write my code here, because I thought, the problem doesn't depend on my code. If it is not, I can put here necessary code.
EDIT:
Error was :
Argument 1 passed to EOAuthUtils::GetAccessToken() must be an instance of
OAuthConsumer, instance of __PHP_Incomplete_Class given, called in
protected/extensions/eoauth/EOAuthUserIdentity.php on line 138 and defined
In line 138 of EOAuthUserIdentity.php was written:
// Upgrade to access token.
$token = EOAuthUtils::GetAccessToken($consumer, $token, $oauthVerifier,
$this->provider->access_token_endpoint);
I put logger pre($consumer,1); before above code. and I had in local:
OAuthConsumer Object
(
[key] => 7........k
[secret] => s........r
[callback_url] =>
)
I had on server:
__PHP_Incomplete_Class Object
(
[__PHP_Incomplete_Class_Name] => OAuthConsumer
[key] => 7.........k
[secret] => s........r
[callback_url] =>
)
the same php version on local and server

Answer 1

You need load class before unserialize object. If u don't do this, object unserialize to __PHP_Incomplete_Class.
see PHP problem with "__php_incomplete_class"
