This is a bit strange (unfortunately I haven't experienced this before) but will see if any of our team members have encountered this issue.
Ok, I figured out what is happening, though I still don't know how to correct it.
If the temp domain is put in without the index - http://bloomingarden.businesscatalyst.com - I get the coming soon graphic.
If I add the index.html - http://bloomingarden.businesscatalyst.com/index.html the site shows up.
How do I get the site to show up when just the domain is put in without the index.html?
Ah!! Thank you so much!!
