[Plugin: Google XML Sitemaps] There was a problem writing your sitemap file. HELP

Do you have access to your PHP error log (or even your webserver error log) – might be worth taking a look in there to see if PHP is reporting additional information about why it cannot write the sitemap.xml file to your chosen location. Also, have you tried creating an empty sitemap.xml and sitemap.xml.gz files with the appropriate permissions in the correct locations?

It is a dedicated server I have access to. Nothing in the error logs either. I’ve tried recreating those 2 files and reuploading them with the right permissions. Same thing:(

I assume that the user your webserver executes as has permissions to write to the destination directories where you’re trying to write the files to – it’s one thing to create a file with 777 permissions – but if the parent directory is owned by another user and it doesn’t have appropriate permissions also – then you’re likely to run into the same problem. Perhaps try changing the configuration to write a test file to somewhere public like /tmp to see if it is a permissions problem….
