Whenever I try to generate a sitemap (manually or automatically), this error comes back: There was a problem writing your sitemap file. Make sure the file exists and is writable.
I have Google XML Sitemaps up and running successfully on other sites (hosted on the same server) and the only difference with this one is that the WP installation is not in the root directory but in a subdirectory. However, I read the FAQ, created the two files and made them writeable (CHMOD to 755) as advised. This did not solve the problem.
I'm really hoping someone has a solution, as this is one of my favorite plugins.
