Every page is showing home url!

My site http:??www.myownthrivingpractice.com has been live for a few weeks & operating normally. Then today I’ve been getting messages from my subscribers telling me all of the links I have e-mailed are just taking people to the home page.

When I go to each page in page editor the pretty url is still showing but if I view the page the url it is showing is the homepage url

e.g. here is my home page url
https://www.myownthrivingpractice.com/
Here is my sales page url
https://www.myownthrivingpractice.com/taming-your-online-practice-marketing/ ?
I’m guessing you will only be able to see the home page using both links.

Any suggestions?
