Sounds like you need to implement the RemindableInterface into your AdminController

class Admincontroller extends BaseController implements RemindableInterface {
	public function __construct(\Tamevent $eventObj) { 
...

There is no prolem with AdminController but SectionsController where i am using Auth::check() to check whether user is logged in or not.

Sorry my bad, did you try to implement RemindableInterface in SectionController?

I don't think that RemindableInterface needs to be implemented for Sections because it has nothing to do with password reminder or anything else. I simply want to check whether user is logged in or not for SectionsController

I think this applies to you: http://stackoverflow.com/questions/23094374/laravel-unexpected-error-class-user-contains-3-abstract-methods

"If you are using the Eloquent authentication driver, update your User class with the following three methods:"

public function getRememberToken()
{
    return $this->remember_token;
}

public function setRememberToken($value)
{
    $this->remember_token = $value;
}

public function getRememberTokenName()
{
    return 'remember_token';
}

I hope this helps.
