Hi

We’re getting literally 1000’s of these (and others) in the logs. How can we fix it?

System.NullReferenceException: Object reference not set to an instance of an object.
at SEOChecker.Common.Repository.Umbraco.UmbracoDomainRepository.GetDefaultRootNodes(IUmbracoContext context)+MoveNext()
at System.Collections.Generic.List1.AddRange(IEnumerable1 collection)
at SEOChecker.Common.Repository.Umbraco.UmbracoDomainRepository.GetRootNodes()
at SEOChecker.Common.Services.EnvironmentService.IsMultiLingual()
at SEOChecker.Common.ContentFinder.RedirectContentFinder.TryFindContent(IPublishedRequestBuilder request)

Thanks.
