PHP Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP

As you know that PHP 7 had been launched. If you are using PHP5 version then you need to change small thing related to your solution. 

deprecated means 

Have you notice the depreciated word in your error -

Deprecated: Methods with the same name as their class will not be constructors in a future version of PHP

 

The means of deprecated that it will be removed in the future. So understand the PHP7 concepts, 

In PHP 5, you never seen the function like.__construct()

 . 

Change the function like.__construct() . You need to use __construct().

Understand this and remove your QA BLOG post error. 

First, navigate your error file - 

qa>qa-plugins>blog-post>blog-admin.php

Jump to the line 22 . 

Use __construct  with the same name as your class :

class qa_html_theme_layer extends qa_html_theme_base {

var $plugin_directory;

var $plugin_url;

function -qa_html_theme_layer($template, $content, $rooturl, $request)

{

global $qa_layers;

$this->plugin_directory = $qa_layers['Blog Settings']['directory'];

$this->plugin_url = $qa_layers['Blog Settings']['urltoroot'];

qa_html_theme_base::qa_html_theme_base($template, $content, $rooturl, $request);

}

I have changed - 

function qa_html_theme_layer($template, $content, $rooturl, $request)

To 

function _qa_html_theme_layer($template, $content, $rooturl, $request)

Hope it will help.
