"No Cache designated vault" exception while uploading graphics

Hi,

I'm using Windchill ProjectLInk 9.1, trying out the Structured Authoring test cases.

When trying to load a graphic file into the workspace "Tech_Pub", after selecting the file and
clicking finish, the UI goes to a page with a "Processing..." gif animation and never returns.

I checked the MethodServer log file (MethodServerLog4j-7344.log), and it has an exception:

2011-06-14 10:16:56,090 ERROR [RMI TCP Connection(26)-10.0.0.82] wt.fv.uploadtocache -
(wt.fv.uploadtocache.uploadtocacheResource/10) wt.util.WTException: There is no Cache designated vault or active folder for Cache designated vault on Local Master Site.

Does anyone know what this means and how to fix it?

Thanks,

Richard Steadman
