    Here’s the full error:
    Warning: Missing argument 2 for current_user_can_for_blog(), called in /wp-content/plugins/collaboration/togetherjs.php on line 34 and defined in /wp-includes/capabilities.php on line 1362

    As it’s shown at the top of the admin & public pages whenever the plugin is active on a standard (not networked) WordPress site running 3.8.1.

    The Fix:
    A quick change of current_user_can_for_blog() to current_user_can() on line 34 of togetherjs.php fixed this issue. Should continue to work for networked sites as this function assumes the currently viewed site (which is what we want).

    However…
    You’re not supposed to pass roles into current_user_can (more info). For example, I had it set to Subscriber and I couldn’t see it as an Administrator (on a non-multisite)… not good.

    So either the role setting should be switched to selecting a capability, or you can add a function that allows you to still ask for a role while the plugin then sorts the roles by user level & checks using that rather than using current_user_can().

    Seems like the quickest/easiest fix is to change to having it be a matter of selecting capabilities rather than roles (in addition to the bug fix above).

    If you’re looking of an example that uses the get_sorted_roles setup, AdRotate has this (you’ll find adrotate_get_sorted_roles as well as the other dependent functions in adrotate-functions.php [again, doesn’t seem like the quickest fix]).

    I’m here to help if you want me to dig deeper. I definitely like the idea behind the plugin & would love to see it furthered!
