@xvilo Blindly tinker with things until they are back to a working state, usually. Sometimes open a Github ticket and then usually find out it was my own damn fault at some point afterwards.
Which kind of problem does your friend have in particular?
@xvilo Usually pop onto an alt account on another instance and ask Mastoadmin or other instance admins for help!
I didn't have enough experience to be confident while juggling a bunch of other priorities, so I went with MastoHost so I didn't have to worry about that stuff. ^^;
@xvilo cry and scream and use a bunch of hashtasgs on mastodon dot com to get help is what i do
General purpose mastodon instance
