RSS not validating

Hi,

I have also get this problem. Recently launched my blog at http://blog.pakpromo.com and the validators are giving me a tough time:

http://feedvalidator.org/check.cgi?url=http%3A%2F%2Fblog.pakpromo.com%2Findex.php%2Ffeed%2F

I have tried uninstalling the plugins but it hasn’t made any difference.

Will appreciate the help.

Thanks,
