WordPress on own dedicated xampp windows server

Hello there, i’m really need help right now.
I install wordpress on my xampp windows server, it is a desktop on my campus. It has a path ‘C:\\xampp\htdocs\wordpress’, and its pointed by http://my-campus.com/my-domain.

For the first time it runs smoothly, the domain http://my-campus.com/my-domain successfully display the wordpress home.

But the i realized, there are few links that should not be any ‘wordpress’ link in it.

For example when i click ‘add image’ button when adding post, and select ‘from url’. The link become default 404 page of my-campus.com. When I inspect the link, it shows:

http://www.ittelkom.ac.id/wordpress//wp-admin/media-upload.php?post_id=85&type=image&tab=type_url

There should not be /wordpress/ in the link, isn’t it? Same thing happen when i want to delete a plugin, when i click “yes, delete files”, it also shows a 404 pages. The link is :

http://www.ittelkom.ac.id/wordpress//wp-admin/plugins.php?action=delete-selected&checked%5B0%5D=hello.php&plugin_status=all&paged=1&s&_wpnonce=3ffb7af6e7

Also on my cform plugin, when i click submit button, there are the /wordpress/ link.

The folder i installed wordpress is named ‘wordpress’m http://localhost/xampp/wordpress

Please someone help me…Thanks and best regards, Wira.

p.s: i’m using a twenty ten thene
