I have a strict doctype type and meta tag compatible with X-UA, and yet, anytime when I load this page I am developing, it is displayed in "Unknown" mode in the document and in the browser. Any solutions and / or ideas?
PS: I work locally. This is after a full page rendering.
Well, I feel like an idiot. Turns out it was a ChromeFrame plugin. I did not understand that he was associated with IE on the Microsoft website. Unfortunately, you must completely remove it from your system, and not just disable it.
