I am new to using WordPress and I was just downloading all the plugins I need for my site, but when I go to Settings -> XML Sitemaps I Received two error messages saying:
1) There was a problem writing your sitemap file. Make sure the file exists and is writable.
2) There was a problem writing your zipped sitemap file. Make sure the file exists and is writable
It also says if I changed anything on my server or blog that I can rebuild the sitemap manually.
If someone could please explain why this is happening, that would be greatly appreciated. Thank you!
