I am new to laravel and I am enjoying it. While working on a social media project I got this error: `htmlspecialchars() expects parameter 1 to be string, object given (View: C:\wamp64\www\histoirevraie\resources\views\user\profile.blade.php)`

I have checked some questions on this site but I have not found a question that solves my problem.

this is what my `profile.blade.php` is made of:

```
<ul class="profile-rows">
    <li>
        <span class="the-label">Last visit: </span>
        <span class="the-value mark green">{{ \Carbon\Carbon::createFromFormat('Y-m-d H:i:s', $user->lastVisit)->diffForHumans(\Carbon\Carbon::now())}}</span>
    </li>
    <li>
        <span class="the-label">Member since: </span>
        <span class="the-value mark light-gray">{{ $user->created_at->format('F Y') }}</span>
    </li>
    <li>
        <span class="the-label">Profile views: </span>
        <span class="the-value mark light-gray">5146</span>
    </li>
    <li>
        <span class="the-label">Living In: </span>
        <span class="the-value">{{ $user->town }}</span>
    </li>
    <li>
        <span class="the-label">Website: </span>
        <span class="the-value"><a href="{{ url($user->website) }}">{{ $user->website }}</a></span>
    </li>
</ul>

```

All the information about the user are given by a controller:

```
public function index($username){
        $user = User::where('username', $username)->first();
        return view('user.profile', compact('user'));
    }

```

Kindly help me solve this problem!
