Hi there,
After upgrade to 3.0.2 I found 2 plugin with errors (openXDeliveryLog, openXVideoAds) in Configuration->Maintenance->Plugins->Plugin Report:
oxDeliveryDataPrepare: Task failed _verifyDataObjects
vastInlineBannerTypeHtml: Task failed _verifyDataObjects
Before ask questions I downloaded both plugin packs from 3.0.2 repo on github.com, install them and chmod 777 plugins/ and www/admin/plugins directories. But errors are still there.
Also there is nothing in debug.log (which is turned on in conf file).
