Websites not working

“on WordPress” meaning wordpress.com or self-hosted? It could be something to do with domain forwarding, masking, a redirect, or something in your .htaccess file. You may want to ask your hosting support to check it out.

Thanks,
It is on WordPress.com. I will check with my hosting support.

You can also ask on the wordpress.com forum. This forum is primarily for self-hosted sites, although there are certainly people here who know a lot about both.

Okay thanks

Why is it that I received an email through Yahoo with a request to answer a remark that someone made on my asian site and that opened my website just fine ?
