    I’m currently working on a new version of the plugin which will have some major changes. To test this new features, I need your help. You can grab the new version here:

    Please note that it is in a very early stage and not suitable for production sites. Please also note that you have to delete your sitemap.xml and sitemap.xml.gz after installation since they are not used anymore (but break the new plugin).

    What has changed:
    Dynamic sitemap generation
    There are no static files anymore. This will solve 99% of the problems users are having. All content is generated dynamically.

    Sitemap Index File
    To reduce the amount of needed CPU and memory, the sitemap is split into sub-sitemaps. The main sitemap file is now only a index file which links to them. With that change you can have an unlimited number of URLs as long as they are spread over multiple months.

    WordPress MU support
    Without having static files, MU and multi-site support is no problem anymore.

    New developer API
    With the new API, developers can build plugins which can create sub-sitemaps to support an unlimited number of items.


    • Install the plugin normally
    • Delete your existing sitemap.xml and sitemap.xml.gz
    • Browse to if using rewrite permalinks, or index.php?xml_sitemap=index if not.

    At the moment, WordPress 3.0 and PHP 5.2 is the only tested configuration. Please let me know if you have problems with other setups.

    What does Google say?

    I’ve seen that the output contains a BOM (Byte Order Mark) which was probably accidentally left by another plugin. The files of the sitemap plugin are all BOM free.

    Could you provide a list ot the other plugins you are using?

    Thanks, could you try to to disable the “Revision Removal” plugin and see if it works?

    Dynamic Sitemap Generation, not work with all hosting services, Dreamhost for example, slow hosting or slow connections. Please insert one option to enable sitemap.xml, and all related files, write to disk.

    Arne, Great beta plugin by the way, I love it! Working great on WP MS except for one:
    This all looks great but Google Webmaster Tools give me some errors, e.g:
    It says:
    Invalid XML tag
    This tag was not recognized. Please fix it and resubmit.
    Parent tag: urlset
    Tag: br

    Some are Tag: b and some Tag: br

    I do have a lot of plugins active in case that may be a problem?





    I have 4 subdomains. The main site works fine, as do two others.

    However, for 1 subdomain I get this error in Google Webmaster for 1 URL only (!):
    Missing XML tag
    This required tag is missing. Please add it and resubmit.

    The URL points to a page with an apparent date in 1999; I wasn’t using WordPress yet at the time ;-).

    Can you help with this? Or is this totally wacky?

    i have 15000 posts and 75000tag and it fails

    Hi Arne,

    Looks like priorities for categories are always set using $gsg->GetOption("pr_tags"), even when it should be pr_cat… See function BuildTaxonomies in sitemap-builder.php.

    All the best,

    Heya there,

    Just downloaded and installed the new Beta of the Sitemap Plugin. All is going fine ( BUT…if i add the Sitemap.xml to Webmaster Tools, it looks like that:

    OK Index Jul 23, 2011 — —

    Normally it would show the Count of the URLs it has found in the sitemap.xml. I have no Error Message so is that normal?


    Hi Arne,

    Also, not sure why hide_empty is set to true with hierarchical then set to false in the call to get_terms (also in BuildTaxonomies in sitemap-builder.php — but the result is that no sitemap entry will be generated for categories which happen not to have any posts directly in them but which do contain sub-categories which have posts in them.

    For many folks using WP in ways that place a lot of importance on categories, it seems like it would be better either not to be making this exclusion decision for them (i.e., err on the side of including these categories rather than excluding them), or enable them to specify for themselves which way they’d like these categories to be handled.

    All the best,

    Dear Members
    So right now, if we still want to use WP MU, which version of google sitemap plug in should we use that is compatible?
    Any links to that plugin that we can use.

    Hi Arne,
    is there a chance that you split up huge sitemaps in several?
    Could look something like this:


    That would probably solve the issue many of us are getting once there are more than just a few posts or tags 😉
    Often it seems to time out or run out of memory or something like this and end up with a strange error like:

    XML Parsing Error: no element found
    Location: hxxp://
    Line Number 1, Column 1:

    There is the Yoast version in his seo plugin that can split up the sitemaps after 1000 urls or so, maybe you wanna have a look if you don’t know this already –

    Thanks so much for the plugin and the support 🙂

    Hi there,

    Google wants its sitemaps to be a physical file. How will that work with this new version?
