New dev site setup but all inks point to homepage

Hi!

I’ve got a live site that is working fine. Time for a few updates, so the guy hosting this site for us has created a new subdirectory, ‘newdev’, and copied the live site into it.

He said he’s updated the database, and in my Dashboard–>Settings–>General, the WordPress Address (URL) has been updated to https://newdev.thecyclery.net.au (while the live site URL is https://thecyclery.net.au.

I find that I can open the homepage of the dev site OK, but if I click any links, it takes me to that page on the live site. E.g, I’m on https://newdev.thecyclery.net.au, then click ‘Ride’ and it takes me to https://thecyclery.net.au/ride

If I manually enter the URL for sub-pages (e.g. https://newdev.thecyclery.net.au/ride) it directs back to the DEV homepage.

I really need to be able to see my dev pages so I know that the work I’m doing is working and displaying correctly… Any suggestions?

Thanks, I hope I’ve provided enough info!!
