My server failed again because it ran out of disk space, because the automated backups are still generating more than they should (whole nother story). I deleted the oldest backup, and ran ./launcher rebuild app. Got the following, multiple times:

```
FAILED

**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one

```

Scrolling up, I see the following stack dump:

Any words of wisdom? I have some unhappy users.

One of your plugins (user-custom-preferences, perhaps?) is incompatible with the most recent version of Discourse. Remove it (or update it to be compatible) and your rebuild shouldl work just fine.

What is the list of plugins you have defined in your app.yml file?

Do a binary search to find the broken one by commenting out bits.

Ah, totally forgot about app.yml. Working with too many different environments. Thanks, Sam, I’ll give that a try.
