Fatal error: Uncaught Error: Call to undefined function wp() in /home/customer/www/monkinsider.com/public_html/wp-blog-header.php:16 Stack trace: #0 /home/customer/www/monkinsider.com/public_html/index.php(17): require() #1 {main} thrown in /home/customer/www/monkinsider.com/public_html/wp-blog-header.php on line 16

I don't know but since last week I am getting this error. My site is hosted on siteground and there are no updates from my side. Also, when I contacted them they said its Wordpress issue and they cant help. I tried to restore backup but only it works for 5 minutes after that error shows up again. Also, I referred to previous articles and everything seems fine the file wp-config and all. Also,I cannot even open my admin Wordpress panel.

Answer 1

That's a malware.

You should scan your server and restore wp-blog-header.php with a default one.

You can download a fresh version here: https://wordpress.org/download/releases/

You won't be able to restore the account until the malware is deleted
