I am getting a strange error with iRedAdmin and roundcube. After installing iRedAdmin, I checked sending mails etc. and everything worked fine. I recently changed the `SSL keys` and DirectoryRoot to `/var/www/public` it stops working and I get:

```
The requested URL /iredadmin was not found on this server.

```

How can I work around?

PS. I can login to roundcube email. But, email is not sent or received.
