I updated on the last version of your plugin and now it is unable to create sitemaps. When I click the button XML Sitemap, a site opens. There is this error:
This page contains the following errors:
error on line 1 at column 1: Document is empty
Below is a rendering of the page up to the first error.
Also in my category sitemap is a category VIDEO with an URL http://Video and I have no idea, why your plugin does that.
Otherwise thanks, its a great plugin.
