After upgrading from WordPress 3.6.1 to 3.7, the following message appears each time a plug-in is updated:
Warning: Missing argument 3 for wpseo_upgrader_process_complete() in /.../wp-content/plugins/wordpress-seo/inc/wpseo-non-ajax-functions.php on line 259
This is being discussed by dozens of others experiencing the same problem on the WordPress.org repository at http://wordpress.org/support/topic/does-it-work-correctly-with-wordpress-37
Likewise, the sitemap.xml is showing the following error:
Error loading stylesheet: A network error occurred loading an XSLT stylesheet:http://.../wp-content/plugins/google-sitemap-plugin/sitemap.xsl
I don't have a problem with sitemap.xml, but I did get the PHP Warning mentioned.
Closing as duplicate of #327. Missing argument issue solved by pull request #328.
Please open a separate issue for the stylesheet error.
FYI: I've just committed the fix - if anyone prefers not to wait for the next official version, but wants the fix *now, you can download the current development version of the plugin and upload the unzipped files to your site via FTP.
