Comment (by paperkawaii):

 I have changed the URL parameter to

 {{{
 'format' => '?mypage=%#%',
 }}}

 Which works fine in 5.4.2 however makes no difference to the problem in
 5.5.

 It still gives a 404 error (after disabling the redirect_canonical)

 Therefore I don't understand the previous comments about rebuilding
 without the page= in the URL.

 I'm splitting posts into multiple pages. Not using the 'next page'
 function as I have a completely custom theme with custom splits for each
 post, integrated with Advanced Custom Fields gallery.. which splits at a
 different image depending on how many images there are..
