? in URL and no www in URL

Hi

I just tried to run a free cookie audit on my website (www.hdsarchitects.co.uk) which didn’t work. I was advised this was because my pages have a “?” in the URL meaning they are seen as separate pages rather than as one website. I was advised that WordPress sites normally work on the system (https://www.cookielaw.org/cookie-audit/) so perhaps it is a theme issue.

Here is an example of a page URL from my website:

https://hdsarchitects.co.uk/?post_type=jetpack-portfolio

It also seems to not show “www.”

Thanks in advance.
