Web Page links not working

Good Morning,
I am experience permalink problems, the website host name has recently been swapped but some like work and some don’t for example the ‘blog’ ’gallery’ section of the site does not work but the ‘our magazines; does? When the page is clicked displayed in the address bar, some say the old URL and some say the new one but the old URL pages work but the new one doesn’t? The confusing thing is the permalinks all have the same URL ‘www.thescenemagazine.co.uk’

My theme is AccessPress Parallax Pro
