Hi Mika,
i found the solution in this link
just i change the data inside this file .htaccess
the correct is :
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
# uploaded ?les
RewriteRule ^([_0-9a-zA-Z-]+/)??les/(.+) wp-includes/ms-?les.php??le=$2 [L]
# add a trailing slash to /wp-admin
RewriteRule ^([_0-9a-zA-Z-]+/)?wp-admin$ $1wp-admin/ [R=301,L]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(wp-(content|admin|includes).*) $2 [L]
RewriteRule ^([_0-9a-zA-Z-]+/)?(.*\.php)$ $2 [L]
RewriteRule . index.php [L]
Note: if any one install the wordpress in sub-directory like this https://www.yourwebsite.com/wordpress/ You must add to .htaccess file in the second line
RewriteBase /your sub-directory
for Example if your sub-directory is wordpress the second line it will be:
RewriteBase /wordpress
Good luck everyone
Artzoon
