All Non Admin User Roles Blocked from Dashboard

Thanks for this plugin it has some really great features.

Although I have ran into one issue. It seems like this plugin prevents all user roles (except admin users) from access the Dashboard. This causes problems for Editors when they try to login and write new Posts and Merchant accounts when they try to manage orders and Products.

Would you be able to take a look at this and see if there is a fix?

Thanks
Greg
