Excuse me, but you just made the tutorial incorrect. You changed the logic properties for the "climbable" region which is the correct property for the plugin to automatically generate a ladder based on the size and shape of the bounding box of the object with that property.
There are two different tutorials on that page. One has you create two climbing regions at the top and bottom of the ladder, and alcscript them, and the other uses a logic property and one single region that encompasses the ladder. If you want to use the two climbing regions, do not put any logic properties on them, and use only alcscript.
I have changed the properties back, and added a note indicating in bold that the AutoLadders section is separate from the above "harder" method.
Perhaps these pages should be split up.

Edit: I have split the ladder tutorials into two separate pages. Hopefully this will avoid further confusion in the future.
