-### PHP "open_basedir restriction in effect" warnings
-
-    PHP Warning:  file_get_contents(): open_basedir restriction in effect.
-
-You need to adjust the
-[open_basedir](https://www.php.net/manual/en/ini.core.php#ini.open-basedir)
-setting in your PHP configuration (`php.ini` file). By default this setting may
-look like this:
-
-    open_basedir = /srv/http/:/home/:/tmp/:/usr/share/pear/
-
-Either add reported directories to the list or disable this setting temporarily
-by adding ";" at the beginning of the line. Don't forget to enable this setting
-again once you are done with the PHP command line operations.

-
-### PHP timezeone warnings
-
-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
-    ; https://php.net/date.timezone
-    date.timezone = 'America/Denver'
-
-Or
-
-```
-echo "date.timezone = 'America/Denver'" > /etc/php.d/timezone.ini

-### nominatim.so version mismatch
-
-When running the import you may get a version mismatch:
-`COPY_END for place failed: ERROR: incompatible library "/srv/Nominatim/nominatim/build/module/nominatim.so": version mismatch`
-
-pg_config seems to use bad includes sometimes when multiple versions
-of PostgreSQL are available in the system. Make sure you remove the
-server development libraries (`postgresql-server-dev-13` on Ubuntu)
-and recompile (`cmake .. && make`).
-
-
-### I see the error "ERROR: permission denied for language c"
-
-`nominatim.so`, written in C, is required to be installed on the database
-server. Some managed database (cloud) services like Amazon RDS do not allow
-this. There is currently no work-around other than installing a database
-on a non-managed machine.
-
-
-### I see the error: "function transliteration(text) does not exist"
-
-Reinstall the nominatim functions with `nominatim refresh --functions`
-and check for any errors, e.g. a missing `nominatim.so` file.
