So, yesterday I had a question how to install the wordpress in the \"/root\" directory. I wasn\'t very successful in that one and I forgo\'ed on that one.
So, right
In my case, the redirect loop only affected wp-admin pages, so I added at the start of the line
if (is_admin) remove_filter('template_redirect', 'redirect_canonical');
and still works, plus the redirect canonical keeps doing its job on the front end!
I hope this helps someone else!
