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 http://www.yourblog.com/sitemap.xml 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.
