Hi,
I have sent you a PM, but meanwhile I found something else: it seems to have to do with the multi-language feature of Joomla. Our website is in two languages (dutch and german) and Sitemap generator only indexes a small part of the Dutch content, then it gets onto the German part and never goes back to the Dutch content. So the German content is completely indexed but the Dutch content only until Sitemap Generator finds the first German content page.
Any idea how to fix this?
Best regards,
Axel
