I just created a clean install of a multisite setup and my subdomains don't work at all. I followed all of the directions at ottopress.com and I have set up a different multisite install with domain mapping and had no problems. I compared both setups and saw absolutely no difference.
But when I try to go to subdomains of tastygumbo.com, none of them work as subdomains. I can go to superdupershark.com for example but I can't go to superdupershark.tastygumbo.com. So the mapping is working perfectly but the subdomains aren't working at all.
Does anyone have any ideas about solutions? I am totally and completely stymied by this one.
[No bumping, thank you.]
