### Website reports "DB Error: insufficient permissions"
The user the webserver, e.g. Apache, runs under needs to have access to the Nominatim database. You can find the user like [this](https://serverfault.com/questions/125865/finding-out-what-user-apache-is-running-as), for default Ubuntu operating system for example it's `www-data`.
1. Repeat the `createuser` step of the installation instructions.
2. Give the user permission to existing tables

GRANT usage ON SCHEMA public TO "www-data";
GRANT SELECT ON ALL TABLES IN SCHEMA public TO "www-data";

See the installation instruction for a full list of required packages.

### Setup.php reports "Cannot redeclare getDB()"
`Cannot redeclare getDB() (previously declared in /your/path/Nominatim/lib/db.php:4)`
The message is a bit misleading as PHP needs to load the file `DB.php` and
instead re-loads Nominatim's `db.php`. To solve this make sure you
have the [http://pear.php.net/package/DB/ Pear module 'DB'] installed.

### I forgot to delete the flatnodes file before starting an import.
That's fine. For each import the flatnodes file get overwritten.
