Creating Language Files Manually:-
I.Copy /usr/local/cpanel/lang/english to /usr/local/cpanel/lang/your_language_name.
II.Edit the copied language file and save the changes.
III.Run /usr/local/cpanel/bin/cachelangfiles as root from the command line.
IV.Either have your users change their language in their cPanel interface (if the option was given to them) or use the "Modify an Account" function in the WHM to select the new language for them.
Important:-
/usr/local/cpanel/lang/english is the default english language file provided by cPanel
As & when changes are made to a language file, the changes must be cached to work properly. This is achieved by running /usr/local/cpanel/bin/cachlangfiles. When
language files are edited through the WHM, this script is run automatically upon saving the changes. This script is also run automatically when cpsrvd is restarted.
Very Important:-
Also new language files should include all the values present in the English language file.
Changes to the English Language file would be overwritten when CPanel is upgraded or resynced. You would have to create a new language file if you wish to edit the file for English Language.
Hope this is of help
