Bad value “https://analytics.twitter.com/i/adsct?txn\_id=l5cxe&p\_id=Twitter” for attribute “src” on element “img”: Illegal character in query: “\” is not allowed.
Bad value “//t.co/i/adsct?txn\_id=l5cxe&p\_id=Twitter” for attribute “src” on element “img”: Illegal character in query: “\” is not allowed.
No “li” element in scope but a “li” end tag seen.
