Permalink URL

Hi!

You can set Custom Structure for Permalink.

Regards.

You mean you have domain name registered by someone else and you hosting with a different host if so all you need to do is change name servers at registrar to point to your host account.
Your host should have provided you with DNS settings.

So under permalink settings I create a custom structure substituting my domain name url for the site url supplied by the hosting company.

Thanks

What is the domain name in your Settings>>>>General as that is domain name that is used.
In permalinks you do not use domain name you suppose to use /%postname%/ so that permalinks use your title of page or post in urls.

The wordpress url is https://www.markmcnee.site90.net
The site url is https://www.markmcnee.site90.net
and the permalink is https://www.markmcnee.site90.net/sample-post/ but my domain is markmcnee.com so I would like the permalinks to be https://www.markmcnee.com/sample-post/

This domain name markmcnee.com is it pointing your host account if so you will need ask your host to change DNS.
Some how markmcnee.com is redirected to https://www.markmcnee.site90.net
markmcnee is subdomain name of site90.net

then you will able to change domain names in Settings>>>General to your domain name.
