Yes it does.

I ended up destroying my backup dev site and reinstalling Discourse. It worked fine as the basic installation.

I then installed the plugins and it suddenly gave me the Bad Gateway error again.  
I then started manually uninstalling the plugins to see if one of them might be causing the issue, but this is the error I get:

```

It looks like the moment I try to install any plugin, it gives this error and I can’t undo it just by uninstalling the plugin.

Any idea what I should do?
