ReflectionException Error

[Deepinder]

Getting below error on Prestashop Backend login however the front is working fine

Whoops, looks like something went wrong.

(1/1) ReflectionException

The autoloader expected class "PrestaShopBundle\Controller\Admin\Sell\index" to be defined in file "/vendor/composer/../../src/PrestaShopBundle/Controller/Admin/Sell/index.php". The file was found but the class was not in it, the class name or namespace probably has a typo.
