I found that my podcast feed (from machigai.com) has some verification problems. One of them is the language setting. The feed is abbreviating "Japanese" as "jp", which Feed Validator says is wrong. Apparently, based on what Wikipedia says, it should be "ja" or "jpn".
According to this link
the language settings should be under "Settings -> General". But they aren't. I'm not seeing anything under the "Week Starts On" dropdown. Any idea why? How can I fix this?
