(array) missing from vBSEO :: Conditional Signatures hook at postbit_display_complete

In the plugin: vBSEO :: Conditional Signatures postbit_display_complete
there is a line:

Code:

$_vbseo_pg = array_merge( $this->post['usergroupid'], 
explode(',',$this->post['membergroupids'])
);

It should be:

Code:

$_vbseo_pg = array_merge((array)$this->post['usergroupid'], 
explode(',',$this->post['membergroupids'])
);

Note the (array) after the array_merge - this must be present or you will get an array merge warning in php5

Which version of vBSEO Conditional Signatures do you refer to? That was fixed long ago in v1.4 (current version is 1.4.2: https://www.vbseo.com/downloads/ ).
