So I just bought my first domain through Bluehost and I go to WordPress to create my blog and I get two error messages and I don't understand what they mean. So basically I'm on the installation page and the first error message says "Oops! Directory exists! Are you sure you want to override its contents?" the other one says "Directory exists! I understand that continuing will overwrite files" with a check mark box next to it wanting me to check it to make sure I understand! But I don't! What does this mean?
