Hi @Shiva Durga Pra 

You are on which patch of Xanadu? Try to repair the plugin once of theme builder.

I have tried the same but , unfortunately it is not working

Are you on Patch 1 of Xanadu? If yes then go to patch 2 or lower down to base version. Patch is not a stable one and many other issue reported.

Is  there any other way to do
