That's not enough information to help you.

Getting errors?

If your blog is wordpress: Sometimes if you moving database from old hosting to new hosting, and the host is still propogated, you will not see the blog content until its propogated.

But let me know if you need help, I'm used to moving wordpress from host to host.

Cheers

Yea, more information would help.

But, one thing I often notice when transferring a WP site is that the permalinks need to be reset. Go to your permalinks section and just click the save/update button (the settings should still be how they were, but they need to be updated to work).

If the issue is something else, just fill us in and we will get to it.
