wordpress button Not Found The requested URL * was not found on this server.

If you've recently moved, transferred or have a new Wordpress installation then you may find the following issue when you click on a menu item / button.

Not Found The requested URL * was not found on this server.

the solution for me . ( on a unix server ) was to add the following as the .htaccess file at root.

# BEGIN WordPress

RewriteEngine On
RewriteBase /wp/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wp/index.php [L]

# END WordPress
