Hi Armin,

I will soon be porting this plugin to Foswiki so will look out for this error. See Item1250 to keep track of the port.

This plugin has now been ported to Foswiki. Try downloading the version at Extensions.BatchUploadPlugin and see if you have any issues. If you do, please open a new item.
