Hi @Nicole and welcome to the Community.
It's most likely a permission setup - other users do not have permissions to see the content that you create. They must have at least View access.
You can create a user group or address this on an individual user level in space's Settings (Admin level required). That's providing that your users have an account on Confluence.
If they're not, you can grant them Guest access.
You can also enable Anonymous access to a space but that means that EVERYONE on the internet will see your content.
(you can also control permissions = restrictions on a page level).
You must be a registered user to add a comment. If you've already registered, sign in. Otherwise, register and sign in.
