In admin/reports/pubdlcnt page,
the urls in the title column are like '/zh-hans/node/32446'. The 'zh-hans' should not display in the url, as a result, the url is invalid. The same as the action and file name column.

In node page, the url of the (5) is also including 'zh-hans'. The url is also wrong.
