Your Secret URL Parameter is invalid. Please scroll to that line and read the help text below it to understand the minimum and maximum length, and the permitted characters in it.

The following are invalid:

• abc
• supercalifragilisticexpialidocioussupercaliflawjalisticeexpialadoshus

• καλημέρα
• d@nc3R!

The following are valid:

• G3-A3
• knockKNOCK
• yJ8zrExTTLfgRcceqrttnpvTs9tSHJpW

Most likely your secret word is too short, starts with a number / special character, or includes characters other than a-Z, 0-9, dashes, and underscores.

Yes, we added the rules for the secret URL parameter in the last version, indeed.

Apparently, a stark but rather, uh, vociferous minority of people would neither read the documentation, nor accept that special characters have special meaning (hence their name) in URLs. Having already tried putting warnings to the blatantly obvious – like the bag of mixed nuts you buy in the grocery store has a warning "MAY CONTAIN NUTS" printed on it – the next step was to actively forbid the use of any even remotely possibly problematic secret URL parameter at all. I have to tell you, every time I have to do something like that I die a little bit on the inside...
