Oh great, It started working I added www to the plugins. Thanks for helping me. I should have asked you earlier so that I could have saved my energy and time. I would like to say you "Thanks" once again.

One more query I have. When using wrapper, moodle opens in same page when I click on links on breadcrumb and Joomla page gets disappered.

Yes, that is in the documentation, at the end, SSO section.
