Pages not displayin

Hi guys,

I have been working locally with a wordpress site and a remote database,

All works fine, however when I uploaded to online I have to upload the entire wordpress site all files etc, and change the site url from localhost to my site, all works,

However when I changed it back to localhost locally it wont work

I cannot get my pages, the homepage displays however all the links generated by wordpress do not,

for example

https://localhost/wordpress/about-us/
