Fix <a href="https://core.trac.wordpress.org/ticket/12061" rel="nofollow ugc">known issues</a> when shortcodes are embedded in a block of content that is filtered by wpautop.
<h4>for Theme Developers</h4>
If you are developing a theme to provide this on a marketplace, you better embed the following code in your functions.php. This code filters only the shortcodes you defined. Otherwise you risk a failed review because the code in the plugin filters content in general which may is not acceptet.
<pre><code>function shortcode_empty_paragraph_fix( $content ) {

 // define your shortcodes to filter, '' filters all shortcodes
 $shortcodes = array( 'your_shortcode_1', 'your_shortcode_2' );

 foreach ( $shortcodes as $shortcode ) {

 $array = array (
 '[' . $shortcode => '[' .$shortcode,
 '[/' . $shortcode => '[/' .$shortcode,
 $shortcode . ']' => $shortcode . ']',
 $shortcode . '] ' => $shortcode . ']'
 );

 $content = strtr( $content, $array );
 }

 return $content;
}

add_filter( 'the_content', 'shortcode_empty_paragraph_fix' );
</code></pre>
Another solution that is acceptet at the envato (themeforest) marketplace comes from <a href="https://gist.github.com/bitfade/4555047" title="a Gist on Github" rel="nofollow ugc">bitfade</a>.

Often times, ideas from WordPress Ideas (https://wordpress.org/ideas/) or bugs from WordPress Trac (https://core.trac.wordpress.org/) take years to make it into WordPress Core. Sometimes even if everyone agrees on the fix it still doesn’t get in. This plugin is the temporary patch you’ve been waiting for. Activate any feature you want and disable any you don’t want.
<ul>
<li>Allow excerpts to show links.</li>
<li>Obscure login errors so an attacker will not know if a username exists.</li>

<li>Some added shortcodes.</li>
<li>Customize login.</li>
