Pathauto Module Required?

Added only required modules as listed in the Modules page. ctools, date, views, rules. Enabled membership_entity, membership_entity_term, membership_entity_types

Made settings change to add a term length, 1 year.

Created a test user.

Tried adding a membership to the test user, via /admin/memberships/add, got the following error:

Fatal error: Call to undefined function pathauto_entity_language() in ... /sites/all/modules/membership_entity/membership_entity.module on line 398

Downloaded/enabled pathauto and token, and tried again, problem resolved.

Disabled Pathauto and Token and error came back when trying to add a membership again, via /admin/memberships/add
