Codeigniter 4 Post Problem

I started use codeigniter 4 so new. Everything work properly on localhost but after insatalling on a host only "post" request not working. I cant get any valu after post request.
Html

Code:

<form  action="<?php echo base_url()."/slider/ekle" ?>" method="POST" enctype="multipart/form-data" >

        <div class="form-group">
          <label>Başlık</label>
          <input type="text" class="form-control"  placeholder="Slider başlığı" name="baslik" value=""/>
 
       </div>

      <div class="form-group mb-0">
         <div>
            <button type="submit" class="btn btn-primary waves-effect waves-light mr-1">Ekle</button>
         </div>
      </div>
</form>

Ekle.php (Controller )

Code:

public function ekle()
    {

        $baslik=$this->request->getPost("baslik");
        $aciklama=$this->request->getPost("aciklama");

        print_r($baslik);
        die();
}

What i mean is everycodes are well working on "localhost" but "post" request not working on my host

After 

Code:

print_r($baslik); die();

 returning page is loading empty.


What could be the problem's sourche?
