Error Create alias "Internal Server Error"

Hello,

After upgrade from v0.15 to v0.16 and update OS(Ubuntu Server 14.04). I have error when edit or create new mail-alias (but the changes are applied). Screenshot in attachment.

Add Alias   
Internal Server Error
The server encountered an internal error and was unable to complete 
your request.  Either the server is overloaded or there is an error in 
the application.

Try to re-run the setup by using the command sudo mailinabox :wink:

Good idea! :blush:

-----------------------------------------------
Your Mail-in-a-Box is running.

But have error again when create alias(but alias has been created) :persevere:

I can see install log ( #> sudo mailinabox) or debug mode?
Where is we can find log “energy” admin panel?

I have only nginx log:
2016/02/08 03:19:08 [error] 9992#0: OCSP responder sent invalid "Content-Type" header: "text/html; charset=utf-8" while requesting certificate status, responder: ocsp.int-x1.letsencrypt.org

and old log nginx:

2016/02/02 12:49:06 [error] 1724#0: *1046 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 164.155.43.13, server: mail.replacemydomain.com, request: "GET /admin/mail/users?format=json&_=1454406292963 HTTP/1.1", upstream: "http://127.0.0.1:10222/mail/users?format=json&_=1454406292963", host: "mail.replacemydomain.com", referrer: "https://mail.replacemydomain.com/admin"
