Category map: The document tree is shown below

An empty page like that can be caused by a too high memory consumption. Do you have very many categories? Try reducing the maximum number of terms on your Settings > XML Sitemap admin page (Taxonomy tab).

yes i have many categories ive put 100 per sitemap

Only 100? That should not be causing a memory issue… There must be something else going wrong. Do you have access to your server/host error logs? I so, what messages does it show there, right after visiting your category sitemap?

Oh, hang on. I do see an error in your category response source code: Fatal error: Allowed memory size of 134217728 bytes exhausted which does mean PHP allowed merory was full…

In your tags sitemap I see 500 entries. Does this mean you have the max terms number now at 500? Or a larger number still?

What happens if you reduce the max terms number to 50 for example?

when i put 50 i have a blank page its not supposed to be a memory issue, ive a dedicated server with lots of juice https://www.tvqc.com/sitemap-taxonomy-category.xml

If you open your category sitemap and view the source (Ctrl+u) you’ll see a “Fatal error: Allowed memory size of 134217728 bytes exhausted…” error message. This means your server’s PHP memory is limited 132 MB. That’s why I asked to see what happens if you drastically limit the number of taxonomy terms in the sitemap. If it then starts working, increase that number by 100 in steps to see when it stops working.

Or, if you can, set the hard memory limit to 256 MB.

Still, your current memory should normally be enough to build a taxonomy sitemap of a 1000 terms. Is there another plugin that is hogging a lot of memory somehow?
