Im getting the following error in SharePoint 2013
Exception System.InvalidOperationException: Operation is not valid due to the current state of the object. at Microsoft.SharePoint.SPUserToken.GetClaimsUserLoginName() at Microsoft.SharePoint.SPSite.CopyUserToken(SPUserToken userToken) at Microsoft.SharePoint.SPSite.SPSiteConstructor(SPFarm farm, Guid applicationId, Guid contentDatabaseId, Guid siteId, Guid siteSubscriptionId, SPUrlZone zone, Uri requestUri, String serverRelativeUrl, Boolean hostHeaderIsSiteName, SPUserToken userToken, Boolean appWebRequest, String appHostHeaderRedirectDomain, String appSiteDomainPrefix, String subscriptionName, String appSiteDomainId, Uri primaryUri)
I also see this error:
w3wp.exe (0x3FF4) 0x1E3C SharePoint Foundation Web Parts emt4 High Error initializing Safe control - Assembly:Microsoft.Office.Access.Services.Application, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c TypeName: Microsoft.Office.Access.Services.Data.ApplicationCookie Error: Could not load type 'Microsoft.Office.Access.Services.Data.ApplicationCookie' from assembly 'Microsoft.Office.Access.Services.Application, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c'.
I have tried IISRESET, adding <add key="aspnet:MaxHttpCollectionKeys" value="5001" /> to web.config but nothing is working
Central Admin comes up with no issues reported
Any help would be grateful
