Failed import in background daemon for expiration #205

Closed CarolinaFernandez closed 10 years ago

Related to SFA API in Opt-in manager. Import is OK, detected to be a circular dependency.

Solved. There were some typos in mon.wsgi and Expiration Manager classes and a circular dependency problem caused by ExpirationManager.

The typos were corrected and the import put inside ExpirationManager's method.
