I am trying to generate a sitemap using the free sitemap generator for the site [external links are visible to admins only]. However, when I put in that URL, only 5 pages are returned. The main content for each page displays through an iframe and I am not sure whether this is causing the issue. There is a robots.txt file on the server but it is not preventing any access. Also, I have the robots meta tag set to "all" or "index,follow".
I have tried running the generator tool on different pages of the site as well, but each time, only a few pages are indexed.
Can anyone help me figure out the problem? Any help would be greatly appreciated!
