Hi all,Just received report from Google about incorrect hreflang implementation on our osticket , and then I found it is true, currently it is:<link rel="alternate" href="//www.example.com/?lang=en-US" hreflang="en-US" /><link rel="alternate" href="//www.example.com/?lang=zh-TW" hreflang="zh-TW" /><link rel="alternate" href="//www.example.com/?lang=zh-CN" hreflang="zh-CN" />The correct URLs should be underscore but not hyphen , means:<link rel="alternate" href="//www.example.com/?lang=en_US" hreflang="en_US" /><link rel="alternate" href="//www.example.com/?lang=zh_TW" hreflang="zh_TW" /><link rel="alternate" href="//www.example.com/?lang=zh_CN" hreflang="zh_CN" />And one more problem is, after I click flag to change language, and then the "lang=xxxxx" will be repeated like this:<link rel="alternate" href="//www.example.com/?lang=en_US?lang=en-US" hreflang="en-US" /><link rel="alternate" href="//www.example.com/?lang=en_US?lang=zh-TW" hreflang="zh-TW" /><link rel="alternate" href="//www.example.com/?lang=en_US?lang=zh-CN" hreflang="zh-CN" />Hope that it can be fixed next release.
