We have downloaded the latest 3.8 plugin for mailchimp integration. We have submitted an API key. Whenever any of the tasks of mailchimp try to run, it errors and logs and error in the Dbo.log . I will paste the error below. It looks like it can't find a core method?
This error happens whenever it tries to run any kind of synchronization.
Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.
System.Web.HttpException (0x80004005): Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'. ---> System.AggregateException: One or more errors occurred. ---> System.MissingMethodException: Method not found: 'Void Nop.Core.PagedList`1..ctor(System.Linq.IQueryable`1<!0>, Int32, Int32)'.
