Easy Blogging returning error if admin is accesses using mapped domain

On one of my subsites, if I go to domain.com/wp-admin and access easy blogging there is an error message that comes up right after "Profile". However if I go to subsite.mydomain.com the error message does not appear.

The error message in question is:

Warning: Invalid argument supplied for foreach() in /home/xxxxxx/public_html/wp-content/plugins/easyblogging/lib/wdeb_callbacks.php on line 14

Any thoughts?
