Ahhh, I see the issue now. That's strange that it's not giving me the error locally or on any of my sites, but the trim() function shouldn't be used there. I've just applied the fix to the admincp/vba_cmps_admin.php file in the download package here, so if you will download the files again and upload the new file that should take care of the issue.
Or if you'd rather apply the fix manually, just look in the file for this code:
And replace with this:
if ((trim($page['userperms']) AND in_array($usergroup['usergroupid'], $page['userperms']))
OR $_REQUEST['do'] == 'addpage'
if (in_array($usergroup['usergroupid'], $page['userperms']) OR $_REQUEST['do'] == 'addpage')
