DevTools failed to parse SourceMap in Chrome console

Hi,
I am using Yii2 basic. I have a offering CRUD. In the view page on my localhost the details are correctly displayed as I coded. But on the domain I have hosted the application as subdomain. Here when I view the page, the details are not displayed correctly. I am using Admin LTE. There were warnings for font awesome. " Failed to decode downloaded font: http://website.com/fonts/glyphicons-halflings-regular.woff2". When I inspect in the chrome browser, I have a warning as follows:


DevTools failed to parse SourceMap: http://website.com/css/bootstrap.min.css.map

The code of view page is as below:

<?php

use app\models\Area;
use app\models\Offeringdetails;

/* @var $this yii\web\View */
/* @var $model app\models\Offering */

$this->title = $model->OfferingId;
$this->params['breadcrumbs'][] = ['label' => 'Offerings', 'url' => ['index']];
$this->params['breadcrumbs'][] = $this->title;
