I've been having a funky day with Dreamweaver. I'm pretty new to the program and web designing in general. It'd be fantastic if you could help me out!

After editing some pages on Dreamweaver and uploading the site, I can't enter any of the pages from the homepage. When I click on a button linking another page, it asks for a username and password for the control panel, then says "Unauthorized access." How did the pages go from being public to limited access?

This is kind of screwing me over. I've tried going back into dreamweaver and changing the host directory/tesing directory and everything, but I have no idea what's going wrong.

Does anyone have any ideas? Any help would be much appreciated.
