After updating commerce-kickstart 2.0rc4 to 2.1 I get different errors. When I'm logged in as admin, I get the following on every non-admin page:
EntityMetadataWrapperException: Unable to get the data property data as the parent data structure is not set. in EntityStructureWrapper->getPropertyValue() (Zeile 442 von /Applications/MAMP/htdocs/profiles/commerce_kickstart/modules/contrib/entity/includes/entity.wrapper.inc).
As anonymous user I don't get this error and I can see the homepage and all product pages.
When I'm not logged in I get an error when I want to add s.th. to the cart:
DatabaseTransactionOutOfOrderException: in DatabaseConnection->rollback() (Zeile 1052 von /Applications/MAMP/htdocs/includes/database/database.inc).
I tried to find help on drupal.org, but none of the posted issues seem to fit. I'm stuck and need help on this one. Thanks.
