Hi Gordon,
force and diskspace are integrated into the API. Since there are no external plugins yet, you can ignore the error message.
Thanks for using WMFS!

The plugins do not appear to be in either the installer nor the zip file, and if I try and do anything it complains "InitializeExternPlugins: Plugin_Dir not found". Am I doing something wrong?
