    Hello Peter,

    On a DNN 4.5.5 portal with DMX 3.04.11, I have discovered a problem. If I do a simple word search, which yields both Collections and documents, when I click on a collection in the search results, I get a critical error: "Conversion from type 'DBNull' to type 'String' is not valid".

    Note: There are multiple DMX module instances, and the above Collection in the search result is associated with a different DMX instance, on a different page. Also, Full Text search is not currently setup on this portal. Any thoughts on what might be causing this?

    Thanks,

    Rob Ralston

    Quick update. I just tested this on a DNN 4.3.7 portal, with same version of DMX and the same problem occurs. Not sure why I never found that before.

    I'll look into it. Sounds like a tricky one this. It's probably something like the breadcrumbs as they can't rebuild.

    Hi Peter,

    Your latest build, 03.05.00 fixes this problem.
