Whenever I save a post with this add on installed, it seems to give me this error:
Non-static method GoogleSitemapGeneratorLoader::CallCheckForAutoBuild() cannot be called statically in [site directory]/wp-includes/plugin.php on line 403
The data is saved to the database and published as normal though.
It also seems like any automatically built sitemaps are generated blank.
What should I do to fix this? Because it really stops me from using my site easily, and I really like the concept of having a Google Sitemap for the news section of my site since the search engine rankings for it aren't as good as the rest.
