Missing Language Files

The extension's XML manifest indicates it installs a certain number of language INI files, but one or more of them are missing. This issue can only be resolved by reinstalling the extension (note that you may have to install a different Package extension).

Why is it a problem?

Language files are used by Joomla! to convert language keys (e.g. COM_EXAMPLE_LBL_HELLO) to human-readable text in the user's preferred language (e.g. Hello, world!). If the language files are missing you may see the raw language keys, or text in the “wrong” language.

Suggested fix

Reinstall the extension, without uninstalling it before, to replace the missing language files.

Notes

It is possible to install an extension before you install a language pack. Joomla! will not copy the language files for this language as it's not installed at the time the extension installed, but the manifest will still list those files. This will make Onthos report the extension as “Missing Language Files”. This is the correct and expected result. Installing the extension again without uninstalling it before will install the missing language files.
