Hi Peter, A couple of days ago I started to get huge numbers of the following exception logged. Another thread on your forum indicated it may be due to files having gone missing in the installation - I reinstalled the version as an experiment, but this made no difference. I have no idea what happened a couple of days ago to set this off. What could be causing this? Thanks --------------------------------------------------- AssemblyVersion: 5.6.8 PortalID: -1 PortalName: UserID: -1 UserName: ActiveTabID: -1 ActiveTabName: RawURL: AbsoluteURL: AbsoluteURLReferrer: UserAgent: DefaultDataProvider: DotNetNuke.Data.SqlDataProvider, DotNetNuke.SqlDataProvider ExceptionGUID: 3668f282-cce2-4101-b170-0b3182d5459f InnerException: Value cannot be null.

Somehow DotNetNuke.Common.HostMapPath is null. This is a DNN bug AFAIK. Peter

Issue has gone away. Upgraded DMX from 5.2.3 to 6.0.4 and the errors in the event log are gone.

About Bring2mind

Bring2mind is the company of Peter Donker, a DotNetNuke enthusiast who has been involved with the platform from the very beginning. At the same time as the market for modules emerged, he realized there was no good document management solution for the platform yet and he set about creating this. In part he based the module on his experience with other document management systems he used while working as a researcher. His module, Document Exchange, was an instant success and has since become the premier document management solution for DotNetNuke. In 2004 he created Bring2mind as a vehicle for the module and is one of the few successful businesses solely based on a DotNetNuke product.
