TokenMismatchException

Browser? Is it Microsoft Edge? I had problems (and I still do) with token mismatch exceptions on it.

All Browsers.

Check your config.php file please, maybe u have some problems there

What is the main reason of this error?

the general reason of this exception is that Laravel use a csrf_field() in the form to protect us from cross site forgery . which generates a hidden input like this

<input type="hidden" name="_token" value="RANDOM_TOKEN"/>

I think you didn't added {{ csrf_field() }} in you form view . so add it it this will work

I'm using Form Facade this input field is generated automatically.

If you check the generated HTML code do you see the token?

Yes.

<input name="_token" type="hidden" value="ion7dCvI4OTRAv5WbeqotTTKdavN30QjXLMy4l7A">

It's a little bit weird... If you don't use the HTMLFacade is it working?

i know this sounds lil weird but just for checking remove the html package and require it again .

Are you submitting the form with ajax?

Same problem again.

Show us your view code.

@khudadad : Did you get it solved? Are you submitting an ajax post request?

Thank you everyone I found the problem, when submitting the form the size of the image was so large, the error solved by small size of image.

I was using this, and Edge seemed to ignore it.

$(function() {
        $.ajaxSetup({
            headers: {
                'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
            }
        });
    });

I solved it by adding the token to my ajax post data as well:

            postData._token = $('meta[name="csrf-token"]').attr('content');

Has anyone found a fix for Microsoft Edge issues causing the TokenMismatchException?

EDIT: My issue had to do with the server time being incorrect (40 minutes behind). Fixing this resolved all my session issues in IE and Edge.
