WordPress core file modified

  • Hello, I just bought Wordfence Premium, since i noticed someone trying to hack my site, and i get a critical issue on 1st scan. WordPress core file is modified – and i do not have permissions to restore to original.

    “wp-admin/includes/upgrade.php” file is changed from:
    @wp_mail($email, __(‘New WordPress Site’), $message); to:
    //@wp_mail($email, __(‘New WordPress Site’), $message);

    Is this serious? it worries me that i dont have permissions on my own site.

    I am new to website developing so hoping for help. Thanks in advance.

  • Hello cwe45,
    the two slashes that are added at the beginning of the line “comment out” that section of code so that line of code is deactivated. What that line of code normally does is to send an email when a new blog is created. I’m not sure if this has been done to your site maliciously or if someone just don’t know what they are doing but if you don’t have permissions to restore the original I would suggest you contact your web host and ask them to help.

    Hello wfasa, thank you for your thorough reply. Yes i reckoned it was a comment out, i’m used to # in Powershell. I think if someone wanted to do something malicious to my site and had access to the core files, they could do a lot worse than that. However i will as you suggest contact my webhost. Thanks

    Great cwe45,
    It doesn’t look very bad I agree but it’s still a strange thing. Let me know how it goes.

    Thanks again wfasa, in reply to letting you know how it goes, i can happily inform i get wiser in regard of webhosting and design by every time i put time and effort into it (thank god). However, being a complete noob i try to learn.
    The file modification error which Wordfence reports as critical seems trivial. I get mails when blogs are commented on anyhow, and my new website seems responsive overall.
    I am finally at a point being happy with the security and the design of my new site. All i need now is putting something in it ??
    Anyways, thanks for being there to help newbees.
    BR, Claus

    Thanks for the update Claus and great job on improving your site and your skills!
