Comments Plus Stopped functioning properly

Hello

I was moving my site from subfolder to root domain. I have coppied and edited index.php and .htaccess file and uploded to root as well as changed the site url.

from that moment ultimate facebook plugin setting showing red cross (not connected) sign. I have went on and changed the url on my facebook app as well..I have changed app secret and changed onto comments + as well..

I am trying last 2/3 hours to diagnose whats going on but failed. I can sign in for fomenting using FB and Google but not with twitter.. Comment not posting anywhere when posting via FB.. Google not showing comment form.. what going on ???

Huge mess !!

Please help me sort this out. Support access is granted.
