I set up a membership site using amember and wp … If a member gets multiple products assigned that should give him more than one wordpress role. And in this case I get the following error message:

Warning: array_intersect_key() [function.array-intersect-key]: Argument #1 is not an array in /home/berggold/public_html/jambam/wp-content/plugins/role-scoper/roles_rs.php on line 330

…

Seems that $roles is not an array…

It looks to me like your $roles->capabilities is an empty array because AMember has created a role that has no capabilities whatsoever. You can modify Role Scoper to deal with that:

in roles_rs.php, change:

$caps = array_intersect($role->capabilities, array(true) );

$caps = array_intersect_key($role->capabilities, array_flip($this->cap_defs->get_all_keys()) );

to:

if ( $caps = array_intersect( $role->capabilities, array(true) ) )
   $caps = array_intersect_key( $caps, array_flip($this->cap_defs->get_all_keys() ) );

thx for your quick response. 

unfortunately this didn't solve the problem. what else could be the problem?

Then try

$caps = array_intersect( $role->capabilities, array(true) );

if ( $caps && is_array($caps) )
   $caps = array_intersect_key( $caps, array_flip($this->cap_defs->get_all_keys() ) );

Okay, I should have given you this in the first place…

if ( is_array( $role->capabilities ) ) {
   $caps = array_intersect( $role->capabilities, array(true) );

   if ( $caps && is_array($caps) )
     $caps = array_intersect_key( $caps, array_flip($this->cap_defs->get_all_keys() ) );
} else
   $caps = array();

Great. Did the line 264 warnings go away too?
