i don’t have any .htaccess there.
Here is .htaccess file
RewriteOptions inherit
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
i don’t think i have installed any security plugin…yeh wp-admin directory is there.
