I set up Wikijs using the ttek script. When I get to the landing page it asks me to login, instead of prompting me to set a username an password. The only thing I could find on the interrnet was to use 'admin' and 'admin123'. I tried replacing 'admin' with 'root' and a few other pemutations and no luck. I also couldn't find where the config file might be, only to change the yaml file, which if course I don't have since I used the helper script? Anyone figured out how to use this one?
