@lazycantaloop Did you install sleeky in the lamp app ? Also, just to double check.. are you using Cloudron (this is a Cloudron forum) ? If it's a general sleeky question, you might have to ask this in their forums.
@nebulon thanks. Perhaps make https://cloudron.io/documentation/apps/yourls/ even clearer by saying something like "if you're using Cloudron user integration you do not need to change the admin password, just login using your Cloudron credentials".
