Thread:Project:Support desk/revision history link

the "revision history statistics " link is down(or not working correctly),its at "External Tools" in page histories at the English Wikipedia for users with en or en-gb as language. It's made by https://en.wikipedia.org/wiki/MediaWiki:Histlegend and goes to https://tools.wmflabs.org/xtools/ec/.. I would fix or help fix it, I need it to see how the page edits and bytes added are going on the article I work on thank you
