I was just working with validation of my site (Since, now it has lots of error) and now I see that there are lots of error that are caused by this plugin.
You can see here : http://validator.w3.org/check?uri=http%3A%2F%2Fautospace.co%2F&charset=%28detect+automatically%29&doctype=Inline&ss=1&group=0&user-agent=W3C_Validator%2F1.3#line-312
Directly jump to error number : Line 383
There are some minor errors like closing a div.
So will you fix it in next update?
