@bull3t: Well it should work. I’ve tested it on my and several other blogs but there are so many different configurations out there that I can’t guarantee that it’s working everywhere. That’s why I’m asking you to check if the new version is working on your system before I declare it as “stable” ??
@alyas2022: This error is probably not related to the Sitemaps plugin since it is not active on the front end. There is also no such database query in it so you could try to disabled all your plugins one by one to see which of them causes the error.
