302 redirect *.at/site redirecting to .comsite

my wordpress site xy.at/site is redirecting to xy.comsite instead of xy.com/site. Is it possible to fix this in the .htaccess file? The .htaccess file currently looks like this: <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ – [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> Thanks in advance for your help…
