I have used this plugin several times without issue and have been very happy with it! However, I am now trying to use it on a site with WP 3.2.1 and I am running into a problem. When I try to build the sitemap, it gives me the following error:
"There was a problem writing your sitemap file. Make sure the file exists and is writable."
I have adjusted the file/folder permissions correctly, as well as used the standard WP .htaccess file for re-writing permalinks as suggested by the learn more link.
I have however managed to build the sitemap using the "enable manual sitemap building via the GET option" in the settings. After following the build link, my sitemap was created successfully. But it does not build otherwise.
Are there any known conflicts with other plugins? Or any other common issues from which this error/situation may arise from?
