Any help?

Thanks in advance,

update: renaming AutofacContrib.Startable.dll (found here as solution) now gives the following:
Invalid object name 'dbo.ScheduleTask'.

Any code or plugins that refer to AutoFac need to have their references changed, as nopCommerce 2.3 uses a newer version of AutoFac which is: 2.5.2.830.

Renaming this assembly seems wrong.

As to the invalid object name ScheduledTask, did you run and upgrade script to the database? You need to upgrade your database from 2.2 to 2.3, which includes a new table ScheduledTask.

I hope this is useful!
