When websites are having technical issues such as the ones Parlor are having, its not uncommon for services such as login or account deletion to stop function.

Keep trying, and at some point it will work. I know, its a hassle having to try repeatedly, but is just how technology works: its not infallible.

Give it a try, if it doesn't work, give it a few hours or even a day before making another.
