I know enough to think I know what I'm doing but then I go and screw things up.
I have a subdomain blog.toolulu.com that hosts my wordpress blog. I also host a splash page at toolulu.com. I was trying to redirect the blog to show up as toolulu.com and get rid of the splash page.
I changed some things in manage domains but once they didn't work, I changed them back (I thought) to what they were before. Now blog.toolulu.com doesn't show up and I can't get into my wordpress admin.
