WordPress Shortcodes allow you to extend the functionality of WordPress. Shortcodes are text within the square bracket. You can paste this shortcode on any page, post or widget. WordPress executes the PHP function associated with the shortcode and displays the result instead of the actual shortcode text. You can find more about WordPress shortcodes at

https://codex.wordpress.org/Shortcode_API

To create a shortcode, open functions.php in your theme folder, add the following code at the end of the file

//[helloworld]
function helloWorld_func( $atts ){
   return "Hello World from shortcode";
}
add_shortcode( 'helloworld', 'helloWorld_func' );

Now your shortcode is ready. You can place the shortcode on any page, post, or widget by placing the following text

[helloworld]

It will display the text Hello World from shortcode.

A shortcode is a normal PHP function, it can do more complex things like connect to MySQL database, fetch data from a remote API, do calculations, etc…

Content Devlivery Network (CDN) allow your web site to serve images from another domain or a sub domain. This speed up web site as your web server don’t need to serve images. Also browsers have a limit on number of parallel downloads from same domain. Having images on a differnt domain bypass this limitation of web browser.

If you use a pull type CDN or a CDN that you manually upload using some sync tool, you need to rewrite all image url to CDN url. There are several plugins available to do this. But you can easily do this with out any plugins.

Edit file

wp-content/themes/YOUR-THEME/functions.php

Add following code to end of the file.

add_filter('wp_get_attachment_image_src', 'staticize_attachment_src', null, 4);

function staticize_attachment_src($image, $attachment_id, $size, $icon) {
    if (is_array($image) && !empty($image[0])) {
        $image[0] = str_replace( 'https://www.YOUR-DOMAIN-HERE/wp-content/uploads/', 'https://cdn.YOUR-DOMAIN-HERE/wp-content/uploads/', $image[0] );
    }
    return $image;
}

This will replace image urls with CDN url.

I have migrated a web site using Avada WordPress theme.

Once site is migrated, i edited wp-config.php file and added following to avoid site getting redirected to old website url.

define('WP_HOME','https://www.newurl.com');
define('WP_SITEURL','https://www.newurl.com');

Now site works, but some of the resources are loaded from OLD site url, this breaks some of the icons.

On Browser Developer tool console, it show following errors

Using URL replacement plugins like Better Search Replace or Velvet Blues Update URLs did not fix the problem.

To fix the it, login to wp-admin. Click on “Avada” on left menu, select Theme Options

wp-admin > Avada > Theme Options > Import/Export

Under Export Options, click on “Download Data File”, this will ask you to save theme configuration file as a .json file, for me it saved fusion_options_backup_02-08-2019.json.

Next click on “Import Contents from File” button. It will show a text area, paste content of the json file you downloaded in previous step here and click “Import”. This will fix the problem related to fonts loading from old url.

If you have a wordpress web site that give blank screen, you can add following to wp-config.php to enable displaying errors.

define( 'WP_DEBUG', true );
define( 'WP_DEBUG_LOG', true );
define( 'WP_DEBUG_DISPLAY', true );
@ini_set( 'display_errors', 1 );
define( 'SCRIPT_DEBUG', true );

This should be added above line

/* That's all, stop editing! Happy blogging. */^M
