Potential screw up

Good morning everyone.
I need the help of this forum.
I’ve 2 domain names registered with Dream Host. One is hosted and is used for a WordPress blog, the other is "non-hosted."
I tried to switch them, so I thought, so that the non-hosted name would become the one for the site. (I decided that I liked that name better)

I obviously did something wrong. When I type my address into the URL, I’m directed to a page with the words “Site temporarily unavailable.”

I’ve emailed Dream Host but I thought it wise to aske here for help as well.

Thank you so much,

It depends on what you did and how you did it. It’s possible that the change has simply not yet updated in the nameservers. It’s also possible that your hosted domain is now pointing at an empty directory. Many possibilities.
