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..
As it was continuously showing not connected at one point I have changed back to subdirectory settings but did not help. Now, I have changed app secret and ultimate facebook is failing to save that details. I have trying last 2/3 hours.
Please help me sort this out. Support access is granted.
