I have read the whole thread but I have still a few questions...

Is this mod working with version v1.3.9b , i'm having errors like:

1: The sitemapproducts.xml has not changed (it is CMOD 777)

2: Google webmaster tool is not adding my latest update...i get a red cross

3: I don't have a compressed xml file, how to create one?
