Why doesn’t the password work?

Either you’ve arrived at an incorrect solution to a puzzle, or you haven’t converted that solution into a proper password.

If you’ve got the correct solution, then the method for turning it into a proper password is as follows:

All page passwords consist only of lower-case letters (a-z) and numerical digits (0-9); no spaces or symbols are used. For any potential password you discover here, remove all spaces and symbols, and convert all upper-case letters to lower-case.
