Dear @mohammad

Seems you’ve changed a lot of there, and something you’ve missed, I can’t edit any files to your server, Please move your site either a cPanel powered server, or to a VPS.

Please check that below code line are exists to your config/app.phpfile

'Form' => 'Collective\Html\FormFacade',
'Html' => 'Collective\Html\HtmlFacade',
'Socialite' => Laravel\Socialite\Facades\Socialite::class,

After moving your site, please let me know, I will fix this.

Best regards
