You can locate your theme’s stylesheet in the following path:
wp-content->themes->qmedical->style.css

Look for the line number 173 and change the width to 550px.

Such kind of problem occurs due to the incompatibility of plugins with WordPress 4.0.
Try uninstalling each plugin one by one by renaming them or moving them to any other folder. You can locate plugins into wp-content->plugins

You don’t need to move the live site on the local server.

1. Using ftp on your local machine or using cpanel you can download the particular WordPress file from live server. After making changes in it you can upload it back to live server.

2. If you want to make changes in the dashboard, then you can login into dashboard using wp-admin. For example:

http://www.mysite.com/wp-admin

It is advised to take backup of your site, before making changes in any file.

1. Locate your theme’s stylesheet in wp-content->Themes->”your theme name”->style.css.

2. Add the following code in your stylesheet file:
.home .page-header{
display:none;
}

Now, you can give title to your home page. It will not show on home page. Also, you will get ride of these two lines.

Can you please post the URL of your site??

Have you already done this?? because i cant see any Home beneath slider.

You can use any plugin to do this. Like display post shortcode plugin and add its shortcode into text widget.

https://wordpress.org/plugins/display-posts-shortcode/

If you want to edit the default recent post widget. Then Here is the path for widget file: wp-includes/default-widgets.php

Do you mean that you don’t want description below title? If yes then follow below steps:

1. In your dashboard, go to setting->General.
2. Look for tagline field and make it clear.

Done.
