Remove /category/ in WordPress URL

In Webmaster Sun article will guide you how to completely remove / category / from the url of the website made ​​with wordpress. Hopefully it will help many more for you in the development of SEO for your webiste.
 

Method 1: Intervening in file functions.php

in your functions.php file and add this code in, or you can attach it to a file of that plugin:

function fix_slash( $string, $type )
{
 global $wp_rewrite;
 if ( $wp_rewrite->use_trailing_slashes == false )
 {
 if ( $type != 'single' && $type != 'category' )
 return trailingslashit( $string );

 if ( $type == 'single' && ( strpos( $string, '.html/' ) !== false ) )
 return trailingslashit( $string );

 if ( $type == 'category' && ( strpos( $string, 'category' ) !== false ) )
 {
 $aa_g = str_replace( "/category/", "/", $string );
 return trailingslashit( $aa_g );
 }
 if ( $type == 'category' )
 return trailingslashit( $string );
 }
 return $string;
}

add_filter( 'user_trailingslashit', 'fix_slash', 55, 2 );

Method 2: Use. Htaccess to navigate

Myself to always use this method for handling / category / because if one can use a will cause a number of issues affecting the code of the website. Moreover. Htaccess should use 301 redirects can fully apply to all sites, whether new or old.

Add the following code into the file. Htaccess with following code:

RedirectMatch 301 ^/category/(.+)$ http://www.webmastersun
.com/$1
# OR
RewriteRule ^category/(.+)$ http://www.webmastersun.com/$1 [R=301,L]
