Scan can't continue – stored data not found after a fork. Got type: boolean

    Hey,

    So I’ve been successfully using Wordfence on some sites now, and have yet to see this mesage (post title)

    Searching for it revealed some messages from the past that seem to have been fixed in past updates. The only advise I could really see was “Kill the scan and wait 1-2 minutes before restarting” – which didn’t work for me.

    I have tried increasing WP memory limit, PHP memory limit and the option in wordfence to request 512MB of memory, none of which worked.

    The problems exist on 2 sites on my test server, their clones on production do not suffer from this.

    I am using WF v5.3.8 and WP v4.1.1 on a windows7 XAMPP server.

    If you need any more info I’d be happy to help out.

    Hi,

    Where is it hanging on the scan? Is it a large file? You should be able to tell a file name that it is stuck on. You could try excluding that file from the scan to see if you can get farther.

    It seems to be different files each time. A few last-scanned files:

    • /better-wp-security/core/class-ithemes-sync-verb-itsec-set-temp-whitelist.php
    • /better-wp-security/core/class-ithemes-sync-verb-itsec-get-lockouts.php
    • /wp-admin/js/user-suggest.js

    iThemes security is installed, but not activated

    I turned on Debug mode and included the last couple of lines of the last failed scan. There’s a 404 in there, too.

    returns ‘OK with http’

    I hope you can spot the problem, if you need anything more, don’t hesitate to ask.

    The 404 looks like your AJAX handler is working correctly. To clarify, these test sites are running locally on a desktop running Windows 7 and XAMPP, correct? Your production servers operate properly. What are your production servers running?

    Yes, they run on win7 ultimate under XAMPP v3.2.1
    The identical production sites run on (from phpinfo)
    System Linux web02 3.13.0-46-generic #77~precise1-Ubuntu SMP Mon Mar 2 23:24:50 UTC 2015 x86_64
    and
    Linux sub.domain.tld 2.6.32-042stab072.10 #1 SMP Wed Jan 16 18:54:05 MSK 2013 i686
    Where sub.domain.tld is an address I’m not I want to display publicly. Better safe than sorry I suppose ;P
