hide the post

Please make sure that you are testing it with an incognito tab.

i dont get it ?
I login with user in group1 an from antoter pc login whit user in grup2.
User group 1 steel see post of user in group2

Settings->Post Type Settings
object type posts
hide complete posts ->Select Yes

i forgot in manage User Groups
for each group is select read accsess only group users

An other pc is fine as well, but if you are logged in as admin you stell see all post. So the best for testing is that you are using an incognito tab. Seems that your permissions aren’t set properly. Please test if the post has the lock hint [L] if you are logged in as admin. Then check if the post is visible if you are not logged in. If it’s hidden there is definitely a problem with your configuration.

users in group1 and group2 are diferent and not admin

Sorry I don’t understand you. Please do the following steps:

• Please test if the post has the lock hint [L] if you are logged in as admin.
• Then check if the post is visible if you are not logged in.

If the post is hidden there is definitely a problem with your configuration.

it’s done
type post with [L] and i see it when i logout from users
