I was also too confuse for all instruction. just i Shared what i did to solve this problem.
I like to say you agin try to set your mysql password.
Just u make uninstall Wapm and Delete the Directory folder then make new install.
check it again on your web browser, it's same or not. if same, protect your mysql with password. for New install u doesn't have any password. Now you need to flow page 2 at end instruction.
I don't say this is the way to do that. but whatever i did just I'm sharing with you.
But
