I use JSitemap in a project with thousands Virtuemart categories and products.
In documentation I have read, that ich can activate the precaching feature for faster execution, but I think it do not work. In SEO dashboard I start precache process and after that i call the xml sitemap or html sitemap. But the receiving needs up to 3 minutes. Then i can see in SEO dashboard, that the status of xml sitemap was reseted to "no cached".

I need help to realy activate the cache feature.
