You need to remove the languageData folder from ‘release’, and revert the client.xml and user.xml files in ‘release’ with the original files.
You can move the languageData folder into a seperate folder in ‘release’. I’ve moved mine to a folder I named Backup.
If you don’t have the original user.xml and client.xml files, I can send you these. Otherwise, you’d have to manually edit your current user.xml and client.xml files to their original settings.
The best thing to do is make a backup of the original files and also a backup of the English files (including the languageData). This way you can swap out when needed.
