> Line 32, Column 15: "ASYNC" is not a member of a group specified for any attribute > > <script async src="https://www.googletagmanager.com/gtag/js?id=UA-54180502-1"><… Hi Manolo, The async attribute is from HTML 5, but your page's doctype declares HTML 4, so the Validator flags that as a problem. Info about async: https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script#Attributes You're choices are: - Ignore the error (most browsers will correctly interpret the async) - Remove the async, or use an older loading mechanism (at the cost of poorer performance) - Upgrade the page to HTML5+ (but the Validator will then flag many more errors/warnings) Cheers - Chuck
