Change wp-admin directory and other files

It’s important for me to simplify the web addresses for my customers. Do someone have a solution for this?

/wp-admin is too complicated for your users? You have a very low regard for them.

You can do a redirect via .htaccess. Or, yes, make a page on your main site (call it example.com/register) and use an in-line login form.

Getting closer to the solution.

This does the job well for wordpress:

The problem is the .htaccess rewrite rules that makes me crazy:
The plugin says you should add

RewriteRule ^admin/(.*)$ wp-admin/$1 [QSA,L]

But then it doesn’t work with sub-directory blogs.

I need a rewrite that:

• Only accepts Mydomain.com/admin and Mydomain.com/user/admin/ not Mydomain.com/user/read-about-admin or Mydomain.com/user/about/admin
• Doesn’t care about lack of trailing slash (Myadomain.com/admin)

My current .htaccess looks like:

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]

# uploaded files
RewriteRule ^([_0-9a-zA-Z-]+/)?files/(.+) wp-includes/ms-files.php?file=$2 [L]

# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]

# ----- FROM STACKEXCHANGE
RewriteRule admin/(.*)$ wp-admin/$1 [QSA,L]

RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(wp-(content|admin|includes).*) $1 [L]
RewriteRule  ^[_0-9a-zA-Z-]+/(.*\.php)$ $1 [L]
RewriteRule . index.php [L]

Take leaf from the default .htaccess:

RewriteRule ^([_0-9a-zA-Z-]+/)?admin$ $1wp-admin/ [QSA,L]

NEVER put your OWN rules in the middle of the WP ones!!

Put that rewrite above “RewriteEngine On”

The basic layout of any .htaccess would be:

# Redirect /admin to /wp-admin for all sites
RewriteRule ^([_0-9a-zA-Z-]+/)?admin$ $1wp-admin/ [QSA,L]

# More stuff
// Hotlink protection
// caching, if applicable, etc

# Begin WordPress
// all the normal WP stuff
