Me: Try logging in with your username and a blank password.
Client: It's not working.
Me: What password did you use?
Client: It's 'blank'.
Me: Well then it should work.
Client: It's not working. It says 'cannot connect to database'.
Me: Where it says 'Password', tell me exactly what you have there.
Client: Like you told me to, I typed in the word 'b l a n k'.
Me: When I said 'blank', I meant that there is no password. The field needs to be left empty.
Client: Oh... right, it's working now!!
