WordPress MU

Hello, have a blog with wordpress distributionsystem established. Did it into the side http://www.webhastasi.net as index set and designed. However, this index appears and there is no blog. How can I solve my problem? example: http://emre.webhastasi.net

Does nobody know that ?

Delete the file index.html from your root directory.
http://www.webhastasi.net/index.html

Don't delete unless you have a backup. If you want to keep that design, you'll need to convert it to a Wordpress theme and enable it on the main blog.

And make sure you follow the steps in the readme to ensure that sub-blogs work right.
