I have weird text on my home page

Hey!

Please go to Appearance > Editor and open Functions.php file and check if there is such code on the top of the file – http://pastebin.com/ZpR2wN7s
and remove it. If you are not comfortable editing the file, please create a temporary admin login and post it here privately so we can check it for you.
Please consider installing a security plugin such as https://wordpress.org/plugins/better-wp-security/ or this one – https://wordpress.org/plugins/bulletproof-security/

Cheers!
