Hi,
I just installed the plugin on my localhost. I prees the GENERATE button in several feeds just for testing and I don't see any file in wwwroot>files>exportimport .
 There is no Permission issue since I can export xml  files in the above folder when using other plugins 
I have chosen YES on "Exported" in Several Categories. 
So I guess I am missing something really simple.  
Can you please help me?
