Parsley.js - zh_HK/zh_CN is not available in the catalog
If you encounter: zh_HK is not available in the catalog or zh_CN is not available in the catalog error when you use caldera form under wordpress, or using it in standalone application, the problem is that parsley.js will load zh_HK.js (or zh_CN.js) in the web page. However, in the i18n directory, there is no zh_HK.js. Even worst, for TW and CN language, the file name is zh_tw.js and zh_cn.js. And even more worst, inside zh_cn.js the name 'zh-cn' is used. So to solve this problem, here are what I have done: Duplicate a new file using "Save As..." from zh_tw.js to zh_HK.js Open zh_HK.js, change zh-hk to zh_HK Rename zh_cn.js to zh_CN.js Open zh_CN.js, change zh-cn to zh_CN There will be no more javascript error. Hope it helps. Thank you.
