@dimchik, You were right. It is an infection.

I am unable to say whether its on first stage or not. I am on Amazon Linux (4.9.20) with nginx 1.9 + php 7.0 + mysql 5.5

The infection didn’t proceed to infect other sites hosted in same host. about 10 wordpress sites.

I do not see similar infection codes.

@generalan, after I replaced things. Everything was fine and normal. I had a “grep” search.

This problem may be serious for someone who just upgraded to PHP 7+. I faced the same, the site was fine in past.

Just add

function mysql_escape_string($string){return mysqli_escape_string($string);}

in top of any functions.php file which you get the error. it should substitute with new function. without going and changing all.
