Hello.
I created a website using WordPress installed through the host. My home page is great, but within the past hour I had to activate a classic editor plugin to update my work because it refused to update. Now, the pages I have that can be found in the navigation bar will not link to the home page. I get the 404 message. Using WordPress I can add things to the pages and update, but when I click the preview button or start from the home page it is not there. I don’t know what has happened. I hope there is enough information to figure out why the pages are not showing up. Thank you in advance.
