> Hi Adam,
> The issue below is a major problem for us (disappearing data resources) just ahedo us releasing CKAN to our staff. I encountered it in my final testing using a real dataset with multiple resources of various formats. Three times I have been loading up data and all of a sudden all the previously loaded resources disappear (they're still in the database, but they don't show up under a datasets resources anymore).
>
> We need this resolved quickly so we can get our staff using it asap (ahead of the other modifiactions we have tal;ked about).
>
> Nigel below seemed to think there may be a fix for this problem? Under our support agreement days, can I get your guys to advise us how to apply the fix, or if necessary to do it for us.

> Thanks
