How do I recreate a Javascript translation file?

• Remove the file from [your_files_directory]/languages/ (if any)

Then execute the following queries on the database (see settings.php for which database is in use):

• UPDATE languages SET javascript = '' WHERE LANGUAGE = '[yourlanguage]';
• UPDATE variable SET VALUE = 'a:0:{}' WHERE name = 'javascript_parsed';
• TRUNCATE cache;

If you now visit the relevant page, the translation will be regenerated.
