Unable to customize frontech home page

Hi,
I am unable to edit the text and few others on frontech theme home page. I have searched the wordpress support and found a related topic but that did not help. Kindly, help me to get over this issue at the earliest possible.

Here are the related details of the thread which is marked as RESOLVED.

Hello,
To fix this problem with wordpress 5.5, copy following code and paste into frontech theme function file :

if( is_admin() ){
	add_action( 'wp_default_scripts', 'wp_default_custom_scripts' );
	function wp_default_custom_scripts( $scripts ){
		$scripts->add( 'wp-color-picker', "/wp-admin/js/color-picker.js", array( 'iris' ), false, 1 );
		did_action( 'init' ) && $scripts->localize(
			'wp-color-picker',
			'wpColorPickerL10n',
			array(
				'clear'            => __( 'Clear' ),
				'clearAriaLabel'   => __( 'Clear color' ),
				'defaultString'    => __( 'Default' ),
				'defaultAriaLabel' => __( 'Select default color' ),
				'pick'             => __( 'Select Color' ),
				'defaultLabel'     => __( 'Color value' ),
			)
		);
	}
}

++++++++++++++++++++++++++++++++
Thanks,
Chakki
