then you can resume with the following command:
```sh
-./utils/setup.php --index --create-search-indices --create-country-names
+nominatim import --continue indexing
```
If the reported rank is 26 or higher, you can also safely add `--index-noanalyse`.
+### PostgreSQL crashed "invalid page in block"
+
+Usually serious problem, can be a hardware issue, not all data written to disc
+for example. Check PostgreSQL log file and search PostgreSQL issues/mailing
+list for hints.
+
+If it happened during index creation you can try rerunning the step with
+
+```sh
+nominatim import --continue indexing
+```
+
+Otherwise it's best to start the full setup from the beginning.

The Apache log may contain lots of PHP warnings like this:
`PHP Warning: date_default_timezone_set() function.`
You should set the default time zone as instructed in the warning in
your `php.ini` file. Find the entry about timezone and set it to
something like this:
-
+
; Defines the default timezone used by the date functions
- ; http://php.net/date.timezone
+ ; https://php.net/date.timezone

+### I see the error "ERROR: permission denied for language c"
+`nominatim.so`, written in C, is required to be installed on the database

-On CentOS v7 the PostgreSQL server is started with `systemd`.
-Check if `/usr/lib/systemd/system/httpd.service` contains a line `PrivateTmp=true`.
-If so then Apache cannot see the `/tmp/.s.PGSQL.5432` file. It's a good security feature,

+This may be a simple out-of-memory error. Try reducing the memory used
+for `--osm2pgsql-cache`. Also make sure that overcommitting memory is
+allowed: `cat /proc/sys/vm/overcommit_memory` should print 0 or 1.
+If you are using a flatnode file, then it may also be that the underlying

## Running your own instance
-### Can I import multiple countries and keep them up to date?
-
-You should use the extracts and updates from https://download.geofabrik.de.
-For the initial import, download the countries you need and merge them.
-See [OSM Help](https://help.openstreetmap.org/questions/48843/merging-two-or-more-geographical-areas-to-import-two-or-more-osm-files-in-nominatim)
-for examples how to do that. Use the resulting single osm file when
-running `setup.php`.
-
-For updates you need to download the change files for each country
-once per day and apply them **separately** using
-
- ./utils/update.php --import-diff <filename> --index
-
-See [this issue](https://github.com/openstreetmap/Nominatim/issues/60#issuecomment-18679446)
-for a script that runs the updates using osmosis.

### Can I import negative OSM ids into Nominatim?
See [this question of Stackoverflow](https://help.openstreetmap.org/questions/64662/nominatim-flatnode-with-negative-id).

-### Missing XML or text declaration
