Finishing up the last few edits on the WordPress site from hell, client is here to see the finished product, senior dev looks over at me "so are the registration/login forms and sign out button working correctly again?"

Me: "yeah I'm just checking one thing first-SON OF A BITCH"

senior: "that does not instill confidence that the forms are working"

Wasn't a big deal, forgot to close a div and, well you know how that works
