I am having a problem with mod_rewrite on subdomains..

I have a folder named 'articles' and have a .htaccess inside this foler that rewrites as:
Code:

<IfModule mod_rewrite.c>
   RewriteEngine On
RewriteRule ^/?/(.*)/([0-9]+)$ ../example.php?id=$3 [L]
</IfModule>

now when i access example.com/articles/a-title/12 it works fine...
I created a subdomain articles.example.com & when I access articles.example.com/articles/a-title/12 the server returns a 400 bad request error...

All my other rules work too without subdomain but with subdomain none works even simply opening articles.example.com returns a 400 error.. can someone please provide some assistance.

Hi,

If you put the content in subfolder 'article' if yes means please add this line in your .htaccess file RewriteBase /(please mention that folder name). It will help you.

Depending on the way Apache is setup on your server, you very well may need to write a .htaccess file in your subdomain's directory.
