Change WordPress user roles and capabilities › Forums › Restrict or Permit access inside WordPress – how to › Wishlist Member › Reply To: Wishlist Member
The known problem with custom roles is missed user levels:
If your custom role does not include “deprecated” user levels try to turn on the same levels set as an “Author” role contains. May be it will help you to resolve a problem.
In other case I need “Wishlist Member” plugin copy to test it and find a reason of described problem. You may send it to email@example.com
