yok sorunun cozumu aslında şu : htaccess 'e
DirectoryIndex index.php
bu kodu eklemek yeterli ama

ama bunu defould hale getırmem lazım

Add a new filename
To add a new filename to the list of index pages that Apache recognizes, perform the following steps:
- Click Add.
- Enter the name of the index file that you wish to add (for example, index.nick).
- Click OK.
- Click Save.
- Click Rebuild Configuration and Restart Apache to configure Apache to use the new DirectoryIndex settings.
- To restart Apache later, use WHM's HTTP Server (Apache) interface (WHM >> Home >> Restart Services >> HTTP Server (Apache)) or run the /scripts/restartsrv_httpd command via SSH as the root user.
