Hi there I am submitting a equation from ckeditor and geting MethodNotAllowedException though my form has method type post and route also post.
Here is my view.
<form class="form-horizontal" action="{{route('set-question')}}" id="submit_form" method="post">
{{csrf_field()}}
<div class="col-md126 col-md-9 col-md-offset-1">
<label class="control-label">Question</label>
<p class="help-block" style="font-size:12px;">Question is required</p>
<textarea name="question" class="ckeditor"></textarea>
<input type="submit" class="btn btn-success" value="Submit">
</div>
</form>
If I type this or some other equation only then other problem arise. I have saved by typing other format even with bengali language that was good. Bellow is my route and then the typography I was able to save in db via this route and view.
Route::post('add-question','Admins\ExamController@addQuestion')->name('set-question');
The successful tries.
But after the highlighted equation or format i got MethodNotAllowedHttpException.
Please suggest me what I'm missing.

Thank you in advance.
