[Plugin: Google XML Sitemaps] Change of domain problems!

Hi all, I changed my domain. It used to be https://www.helpfuladvice.info and now it’s https://www.usefulanswers.info.

The XML sitemap failed, so I uninstalled it deleted all the files and reinstalled it. But I still get the same error.

Error loading stylesheet: A network error occurred loading an XSLT stylesheet:https://www.helpfuladvice.info/wp-content/plugins/google-sitemap-generator/sitemap.xsl

As you can see, it’s still going back to the old URL to find the stylesheet. I’ve updated everything in the settings to the new URL. I just wondered how to I fix this. I thought an uninstall and reinstall would do the trick?
