Still failing after upgrading to 1.01 and uninstalled all other extensions and cleared cache and I get:
Unable to find file WA_SiteTools.htm in the Configuration/Floaters directory. The floater will not be shown. [OK]
Unable to find WA_SiteTools_Progress.htm in the Configuation/Floaters directory. The floater will not be shown.
Wow what a pain..., uninstalling everything just to have errors pop up and the same blue box for Site Import.
New update needed 1.02
