If you are running on DXP, can you open the log stream and look for any errors?
Couple of things you can try. Depending on your experience, you may just ignore me:
Hello, Are there any URL intercepters included after March? Can you check if this was set to child tree components other than the root. It sounds like if start page is working then this shouldn't be a problem with domain configuration. Since this is happening only for child components, Are there chances if pagetypes were changed with no view file? Is this redirecting them to somewhere else?
Another problem could be if the StartPublish date is being manipulated with code. See the blog which mentions the scenario https://blogs.perficient.com/2022/05/13/optimizely-page-publish-options-dos-and-donts/
I get a 404 error for pages other than start page when the "View on Website" link is clicked.
Is there way to resolve this ?
Any help would be highly appreciated
