What do you mean by stopped working, is there an error? Is this regarding a plugin or theme?

i have used if statements in functions.php where if(current_user_can(‘read_private_posts’) example.
This have worked great for some time. But suddenly today, it can no longer seem to regonize and user capability. So the if statement simply don’t work anymore.

What makes you think that the function has stopped working, and not that the user has incorrect permissions? Have you checked that the user has the permissions you think they do. Try installing the User Role Editor plugin and checking that the users and roles have the correct permissions.

If i set up an if statement looking like this if(current_user_can(‘read_private_post’)){}
It do the same thing for all users. Either it will come back true, or false.
I have checked each user and see they have their capabilities still (using User Role Editor Plugin)
I have also checked the database to check if the problem was it not saving the meta data on each user object. But that looked fine aswell.

If it returns false then the function is still working and that is expected behaviour of the function: https://codex.ww.wp.xz.cn/Function_Reference/current_user_can (it returns boolean)

it returns the same whether the user object have the capability or not.
So it returns true or false, depending on if i write with “!” or without, for both the user with the capability, and the user without.

I recommend you read the underlying code of the current_user_can function so that you truly understand what you want to do: https://core.trac.ww.wp.xz.cn/browser/tags/5.2.1/src/wp-includes/capabilities.php#L639
The result is filtered by “user_has_cap”. Some other plugin or your theme could be causing improper results.
