1. Failed to execute query for user input... This error is due to non-existence of Quota_Policy table in cm_storage_quota Scheme. Doing a reset schema on Quota_Policy Dictionary entry in cm_storage_quota Scheme will create new Quota_Policy table.
2. "error getting quota policy information. please see the log file for more details" can you paste the error in the log file or attach the wfa.log and server.log files ?
