I was trying out various themes on my blog. When I went to reactivate one of the previous templates I got this error:
"Fatal error: Call to undefined function get_header() in ...public_html/myballetwear.com/index.php on line 1"
I have four themes available, and every one of them, even WordPress default, now gives the same error. How is this possible, since they all have their own index.php and header.php files?
I can see and read both files on cpanel and from the dashboard, but the blog is completely off the air. Help?
