[Wed Jun 08 07:42:40.568213 2016] [:error] [pid 4556] [client 66.249.65.45:56847] PHP Fatal error: Call to undefined function get_header() in /nas/content/live/infinitelabs/wp-content/themes/Newsmag/index.php on line 6

how can we fix it?

Hi

This errors happens when you try to access the theme’s index.php file directly, usually it displays a Fatal error: Call to undefined function get_header() and it shouldn’t be picked up by google’s crawler.
You can find more info about this in this tread: https://forum.tagdiv.com/topic/fatal-error-3/ and add a redirect rule for it.

Hope this help.
Thanks!
