Describe the bug
When opening pages on innersourcecommons.org, the chinese language is chose as the default language regardless of the browser language. This behaviour was confirmed by multiple users using different browsers. Example to reproduce: https://innersourcecommons.org/learn

Expected behavior
The language should be chosen based on the browser language with English being the default, if the browser language doesn't match any of the languages supported by the site.
