Thanks Kyle.
I was able to reinstall Protostar using your feedback and it worked.
Anyways, I used Protostar and disabled JQuery Easy Plugin and it worked properly. With JQuery Easy turned on, it didn't work. We used it as recommended by Smartaddons because whenever we display CB Profile and Edit, the dropdown submenus doesn't work anymore and Jquery Easy solved that. But on protostar it also gives an issue.
I reported this to smartaddons and I'm not sure what will be there resolution. I'm hoping they will not say that this is a problem with CB. In any case, let me know if you have any comments or suggestions regarding this.
Thank you very much.
