I think it’s time for some more complaint driven development!
Complaint: A disproportionate amount of posts here on meta are people whose discourse installs are broken.
Tired old Solution: We generally ask them to disable plugins and do a container rebuild. This tends to solve the problem 90%+ of the time.
Can we do better? I think so!
I would take it even further and put the advice on all error pages we display, but if you’re not an admin user, hide it behind a “Are you the administrator of this Discourse? Troubleshooting Tips” link.
