Since we upgraded to the newest version 5.1.0 - the sitemap generator is not working properly.  When I scan our site, I can see all the components in the analyze tab - all of our products are there, they are all 200 in status. But when I generate the sitemap, they are not in the sitemap. There are a bunch of pages missing in the sitemap. I can see all of them in the analyzer but they are not listed when the sitemap generates.  They are not being blocked in any way and I do not have any settings (that I know of) set to not compile them.

Any insights would be very appreciated!

It is difficult to help you without a website URL to test against, but usually what you describe could happen because of a website change - e.g. one of the following:

• robots.txt
• noindex / nofollow
• canonical

Mos likely, the change in the website was introduced at he same time you upgraded. Anyhow, if the problem persist please email us your website address here:
