PHP Fatal error: Call to undefined function get_header()

Hello Aakash,

First of all, please ensure that you have respected our list of requirements for our product, like this -> https://forum.tagdiv.com/requirements-for-newspaper/ Also, try to update the theme to the latest version of it and also, all the required plugins which come bundled with the theme, clear all your caches and test it again. Basically, the latest Fatal error is happening due to the old version of Visual Composer. Try to update it and check the results.

Thanks for your understanding!
