Thanks for your pull request. Unfortunately we can't merge it that way.
Please do not make changes to existing translations. Instead it would be better to create a new key for the missing part. Otherwise it would be missing in all other languages. Additionally we won't merge pull requests for translation files other than en.json. All changes done to other files will be overwritten as soon as we push our translations from http://translations.piwik.org
I expected a reaction like that. :smirk: How shall I name the new key, "General_WarningFileIntegrityNoManifestDeployingFromGit"?
Sounds ok. Don't have a better name for it ;)
Should be fine now.
