When new Page is created two things should happen: - Page should be sent for Publishing - Session Preview should be generated for new Page and you'll be redirected to it
First step might fail if there is no Publication Target configured for new Page Second could fail if:
- you turned off Session Preview in the settings
- Session Preview is not correctly configured
- you have different from default Page path routing settings on the staging web site. By default it's Publication Path + Structured Group(s) Path + Page filename
