    Using Wordfence 3.4.5

    After upgrade to the Twenty Eleven 1.5 theme, I get the following warnings for several files:
    – This WordPress core file has been modified and differs from the original file distributed with this version of WordPress.

    Will you update your detection over time, or will I have to solve this myself by ignoring the change?

    Is the update an official update? When looking at the repository, WordPress still says the latest version is 1.4.



    Yes, this is an official update.



    WP 3.4.2
    Wordfence 3.4.5
    TwentyEleven 1.5 (official)
    TwentyTen 1.5 (official)
    —> Though I use a custom template and TwentyEleven/TwentyTen is deactivated

    Yep, same thing happened to me. I saw the WP alerts that TwentyTen and TwentyEleven needed updating.

    I don’t use those themes, but thought I’d update ‘everything’ (a Wordfence update was due roughly around the same time).

    Got the alert a couple hours ago (even though I updated everything about 12 hours ago).

    Couple Examples:

    * WordPress core file modified: wp-content/themes/twentyeleven/functions.php

    * WordPress core file modified: wp-content/themes/twentyten/functions.php

    Yep, official update (for TwentyEleven and TwentyTen).

    Very strange. Am considering just deleting those two themes (since I don’t use them) — but it’s always good to have something in there other than a custom theme (for testing purposes I guess). Not sure if that’s a silly habit of mine, or good-practice in WP. (I know in Joomla we’d rarely ever delete the default themes Beez and so on — cause they get used for late-night live testing when the ‘main’ custom theme has issues).



    Just confirming I am now getting multiple emails (from all my WordPress sites, most on totally separate servers/hosts) with the exact same issues being flagged by Wordfence, because I had updated the TwentyEleven and TwentyTen themes (though deactivated) on all accounts for good house-keeping with updates and so on.


    I did a bit of searching and found that in the Changelog for Wordfence (back in version 3.2.4) it notes:

    Fixed issue that caused twentyten and twentyeleven themes to be shown as missing core files if they have been removed and theme scanning is enabled.

    Hmmm – looks like the latest Wordfence 3.4.2 has a new problem with those same two themes.



    Seeing same issue here. Would like some confirmation from WordFence authors that this is a problem. In the meantime I will just delete the theme.

    Hi folks,

    We fixed this issue with 3.5.1 which went out today. Please upgrade and if you can post a reply confirming it’s fixed for you I’d be most grateful.

    Thanks for the reports!




    Looking good. Thanks guys for the quick-fix!

    Just tested this on my WP installations and all looks to be in good shape.




    Hi Mmaunder,

    After updating to 3.5.1, I’m still getting “File Modified” warnings about the following plugins:

    1. Akismet — 4 different files
    2. WP Super Cache — readme.txt
    3. TimThumb Vulnerability Scanner — cg-tvs-timthumb-latest.txt

    I know I have the latest versions of the plugins, especially Akismet, as I have just updated it.

    By the way, I LOVE Wordfence and thank you so much for such wonderful security plugin! It’s on my must-have WP security checklist!
