Configure > Internationalisation > Languages tab

Whatever language I try to enable, I always get the following error:

Internal error: xx is missing the '_language_name' from it's translation. Language will not be usable.

where xx is the language code (nl, fr, ...)

Any ideas?

This can be caused if the maketext() call fails for any reason. We are just assuming that no results is a missing _language_name field. Check your System.PerlDependencyReport results to see if any of the language dependencies are missing. In particular: CPAN:Locale::Language, CPAN:Locale::Maketext::Lexicon and CPAN:Locale::Msgfmt.

The following patch might reveal more about what's failing:

Strange. This is what I checked:

PERL DEPENDENCY REPORT The only missing one I "suspected", was MultiLingualPlugin, but this one didn't solve the problem, so I uninstalled it again. Apparently, it is meant for multilingual content, not for a translated interface.

The other missing/obsolete modules are: - CPAN:IO::Socket::SSL, CPAN:DBD::SQLite, CPAN:DBI, XSendFileContrib, DBCachePlugin, SolrPlugin, CPAN:Spreadsheet::ParseExcel, CPAN:Spreadsheet::XLSX, CPAN:mod_perl2 But I don't suspect these ones, or am I wrong?

PARTICULAR PERL MODULES When I enable Interface Internationalisation, it tells me the mentioned modules are installed: - Locale::Maketext 1.28 installed for I18N translations - Locale::Maketext::Lexicon 1.00 installed for I18N translations - Locale::Msgfmt 0.15 installed for I18N Language file compression

PATCH If I'm using the patched LANGUAGE.PM checker file, I still get the same result, no more extra error output, although I was definitely using the patched file.

Any further ideas?

If you save the config with the languages enabled, do they show up in the language selector? (ie, is this a problem with the checker, rather than an actual problem with the language files.) The errors reported by the checkers won't actually stop configure from saving the configuration.

Right, MultiLingualPlugin has nothing to the base languages support. Nothing jumps out in the list of missing modules.

SOLVED

Apparently, there must have been something wrong with the CPAN modules I installed in the local CPAN library of my Foswiki installation.

After I asked the hosting company to activate CPAN:Locale::Language, CPAN:Locale::Maketext::Lexicon, CPAN:Locale::Msgfmt in the base path, I was able to enable Interface Internationalisation and choose languages without errors. Immediately after saving the changes, the language selector appeared (which was not the case when I saved the config when the errors were mentioned).
