Missing required parameters for [Route: about] [URI: en/content/{contentSlug}].

Obviously... You need to add the slug from your data.

You are accessing a route that requires a parameter {contentSlug} and you are not passing the slug to that route

Do this

@php
$page = Page::first();
@endPHP

<a class="nav-link" href="{{ route('about', $page->slug }}">

This is just an example of how you want to use that route, you should do it however you normally would with MVC pattern

I do this but not solved error

@michaloravec can you help to fill me in? Is this some sort of spam?

@devingray_ This user has really bad behavior on this forum.

His usually phrases are

Answer my question

I am in hurry

Everytime when he doesn't get an answer, he changed a text a little bit to got the thread to the top, or he created a new one.

He ask really silly question like this, and it's really obvious what the problem is. So many people told him that he has to learn and he just promises he will do that in the next project.

It's same person as @oxbir (it's this account), @iroxbir and @irankhosravi

Just for example he created this thread

https://laracasts.com/discuss/channels/laravel/how-to-send-email-using-laravel

Which is same as 5 years old thread on stackoverflow

https://stackoverflow.com/questions/35830567/how-to-send-email-using-laravel/35830811

And I can continue a whole day.

Got it. Thats a shame, this community is awesome, so having that attitude really sucks. Will pay attention to this in future

@devingray_ By the way look on this 4 weeks old thread

https://laracasts.com/discuss/channels/laravel/how-to-define-name-for-slug

It's the same problem from the same user.

@michaloravec Yeah I had a poke around, and I am not sure what the issue is here, I actually doubt that these are real world problems, it seems all posts are just trolls for attention
