FOS UserBundle Unable to login

Question

I'm back with another issue regarding my UserBundle : Everything went perfect while installing and configuring FOS bundle through Symfony2, it even let me create 2 users that were properly inserted into my DB. However, every time I try to login into either of these accounts, I get the following error ``` Warning: Erroneous data format for unserializing 'VillaPrivee\UserBundle\Entity\User' in /Users/Vianney/Projets/VillaPrivee/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php line 869 ``` This is what the line 869 refers to : ``` /** * Creates a new instance of the mapped class, without invoking the constructor. * * @return object */ public function newInstance() { if ($this->_prototype === null) { $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name)); } return clone $this->_prototype; } ``` And this is my User entity : ``` namespace VillaPrivee\UserBundle\Entity; use FOS\UserBundle\Model\User as BaseUser; use Doctrine\ORM\Mapping…

Accepted Answer

If you are using PHP Version 5.4.29 or 5.5.13

In: "/vendor/doctrine/orm/lib/Doctrine/ORM/Mapping/ClassMetadataInfo.php" find function "newInstance" (around Line 827) and edit as followed until the Fix is merged by doctrine.

```
public function newInstance()
{
    if ($this->_prototype === null) {
        // $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
        if (PHP_VERSION_ID === 50429 || PHP_VERSION_ID === 50513) {
            $this->_prototype = $this->reflClass->newInstanceWithoutConstructor();
        } else {
            $this->_prototype = unserialize(sprintf('O:%d:"%s":0:{}', strlen($this->name), $this->name));
        }
    }
    return clone $this->_prototype;
}
```
