It almost seems like Magento is taking the
sitemap.xml from cache even though I'm regenerating it.
In the sitemap admin page, I'm pressing
generate. But the function
app/code/core/Sitemap/Model/Sitemap.php is never called.
Curiously, if I remove sitemap.xml, it will reappear with the old content,
generateXml() still not being called.
Is there a caching system which could be responsible for this? Am I using the wrong file or am I assuming the function should be called even though it shouldn't? Any other reasons?
