Hello,
It seems that you have fixed this problem. I tried reaching ur sitemap url. Its wrkng fine.
Now am experiencing the sampe problem. Could you plz let me know what you have done?
My Sitemap URL: http://www.seobyelan.com/sitemap.xml
Note: My blog has been hosted in windows. I could not make sitemap.xml and sitemap.xml.gz with 777 or 755. Simply its writable through coding by hosting provider.
It will be very helpfull if u help me in fixing this.
