I have a content type and one of its Field Type is "Term reference" (field_portion_name) and its referenced to taxonomy (field_tags) using as drop down widget. Right after I enabled the module if I browse the site I got this error message in my log report

EntityMetadataWrapperException: Unknown data property field_portion_name. in EntityStructureWrapper->getPropertyInfo() (line 339 of C:\DevDesktop\docroot\sites\all\modules\contrib\entity\includes\entity.wrapper.inc).

If I disable the module then it works fine.
