Next was Google XML Sitemaps - Version 3.0.3.1.

Once again, there didn’t appear to be any issues with this plugin and WordPress 2.5.

One problem I did experience with this version of the plugin was getting the plugin to write the sitemap.xml file. I uploaded an empty sitemap.xml file, and tried setting the permssions with FileZilla. I tried setting them to 666 (the usual value I use with no problem). No dice. Tried 755, and 777 - and still the plugin couldn’t write the sitemap file.

I checked the comments on the plugin’s site + did a Google search - and sure enough - there were others that had had a similar problem. What you need to do is do a manual update - by clicking on the link to rebuild the sitemap manually - found on the options page.
