I know this is late for the original poster; however just in case I might be able to help someone else I shall attempt to reply.
The instructions that Dream Host sends to people in an email after they have just one clicked installed Joomla I believe has a major error in the instructions.
The instructions state this...
Leave everything alone except for the following:
Path : remove JUST the "/.something/" part of the path... leave the rest!
Your E-mail : enter your email address.
Admin password: you may want to change this.
Click "Next >>"
I believe that this section is wrong.
Path : remove JUST the "/.something/" part
I believe it SHOULD say.
Path : remove JUST the "/.something" part.
because if you do as they say and remove "/.something/"
you are making two sections into one that shouldn't be.
if we were to remove "/.something/"
we would be left with this
the home section and the jimmy section should not be squished together, but rather it should be separated by the / symbol.
I do hope this made sense and helped others out. I am not 100% sure this was the problem, but that would be my educated guess.
