This is getting pretty urgent. I really appreciate if someone sheds some light to my problem.
To elaborate: I have tried changing the permissions of root directory of the WP blog to 777, that didn't work. I created two empty files named sitemeap.xml and sitemap.xml.gz and set their permissions to 777 that also failed. Full error message is below. I get this whenever I try to manually re-build the sitemap.
I use this plugin in my other sites and never had a problem. I'm stuck. Please help.

The building process took about 0.01 seconds to complete and used 41.5 MB of memory.
If you changed something on your server or blog, you should rebuild the sitemap manually.
