Somehow my css got separated from my index and some other non-existent file is now in that tab. My question is how do I get rid of JosephCross_Milestone and have the stylesheet there instead?
Answers are in your code. Are you working within a defined local site folder in DW? Without this critical 1st step, DW cannot properly manage your links and & assets for you.
Can you show us the code from your index page? Don't use email for this, it won't come through.
