Hello,

Do you have a problem to use the language (for this, your Joomla should use this language first) or do you want to modify some translations ? (in this case, you can use the Joomla override system : icagenda.joomlic.com/docs/documentation/...joomla-administrator

If you mean missing translated strings in the language pack you have downloaded, which language it is ?
And so, you can if you want contribute to the translation here: www.transifex.com/joomlic/icagenda/

Best regards,
Cyril

You're welcome!

This is a often question people have when installing a third-party extension, as the joomla language should be installed first, before to install an extension using it

Recently, the language install process was changed and improved in Joomla 3.6, to allow more info on multi-languages site, and to help users to create the multi-languages site while installing it the first time

Best regards,
Cyril
