I cant login to my wp-admin.

I was trying to configure my setting inside my dashboard and on that page I saw something like to install your blog into wordpress, exsample.com/wordpress I now changed my domain which was in the box to https://www.myaffiliategamelan.info/wordpress.

Since then the blog is not loading, and after about three days I login to namecheap with whom I registered my domain with and change my DNS back to their own. Because this blog was been hosted by hostgator and I change my DNS back to hostgator DNS with the hope that it ‘ll correct it self automatically but alas I cant even login to my wp-admin any longer, and the blog it’s still not loanding hence this post. Every assistance is welcome.

Thanks.
