Trying to host my website off of my home server just as a presentation/testing method. My problem is accessing the magento database on phpmyadmin. When I try to open it up without a username/password (root) setup in phpmyadmin, I get a This Page Cannot be Displayed error when trying to open up my webpage in a browser. But if I DO give phpmyadmin a username/password I get the "There has been an error processing your request" message when I try to open up magento webpage in a browser.
You're not a developer in today's environment until you learn how to run with security fully enabled by default. No goofy bypasses.
phpMyAdmin obviously is enforcing this. So you have to set a password to access the database.
Your error processing request is referring to a file with that number contained in var/report/ and likely is telling you that Magento now cannot access the dabase because it needs to be given the user name and password => See app/etc/local.xml for where this needs to be entered.

We will force Magento to show full error message using local.xml file
