Fatal error on activation

    I get the following error trying to activate WordFence:
    Plugin could not be activated because it triggered a fatal error.

    This happened for versions 6.0.25, 6.1.2, and 6.1.3

    I tried installing an older version (5.3.12) and it installed and activated but then I got the white screen of death. Debugging gave me the following:

    [14-Apr-2016 18:38:49] PHP Warning: require_once(lib/wordfenceConstants.php): failed to open stream: No such file or directory in E:\Inetpub\edutech\wp-content\plugins\wordfence\wordfence.php on line 23
    [14-Apr-2016 18:38:49] PHP Fatal error: require_once(): Failed opening required ‘lib/wordfenceConstants.php’ (include_path=’.;C:\php\pear’) in E:\Inetpub\edutech\wp-content\plugins\wordfence\wordfence.php on line 23
    [14-Apr-2016 18:38:49] PHP Warning: require_once(lib/wordfenceConstants.php): failed to open stream: No such file or directory in E:\Inetpub\edutech\wp-content\plugins\wordfence\wordfence.php on line 23
    [14-Apr-2016 18:38:49] PHP Fatal error: require_once(): Failed opening required ‘lib/wordfenceConstants.php’ (include_path=’.;C:\php\pear’) in E:\Inetpub\edutech\wp-content\plugins\wordfence\wordfence.php on line 23

    The file wordfenceConstants.php exists in the right folder and has full access permissions.

    Things I have tried (with no success):
    – disabling all other plugins
    – changing themes
    – increasing memory limit: define( ‘WP_MEMORY_LIMIT’, ‘256M’ );
    – manually deleting the WordFence folder and downloading it directly
    – upgrading WordPress (the same things are happening in WP 4.4 and 4.5)

    I have multiple other WordPress sites (not networked) successfully using WordFence. This site was running WordFence successfully for a while but one of the upgrades (I believe 6.1.2) caused the website to white-screen. Unfortunately, I was passed this problem from someone else so I don’t know the exact details for when the problem originally started.

    thanks for your help,
    Charlie

  • I too am getting this on a fresh install of Wordfence 6.1.3 into WordPress 4.5 on a Windows server.

    Message:
    Plugin could not be activated because it triggered a fatal error.

    Here’s the full error message:

    Fatal error: mcrypt_create_iv() [function.mcrypt-create-iv]: Could not gather sufficient random data in D:\Hosting\12345678\html\blog\wp-content\plugins\wordfence\vendor\wordfence\wf-waf\src\lib\utils.php on line 253

    Hi Charlie,

    What was the message from the fatal error when installing newer versions? 6.0.25 was a minor change from 6.0.24, so since you were having issues with that version as well, there may be a change on the server

    Wordfence isn’t officially supported on Windows servers, but we have heard of others having success with prior and current versions. Most unusual issues we see on Windows are due to running an older version of PHP, especially 5.4 or below. Do you know what version your site has?

    @drbellerive: If you are using an older version of PHP, can you try updating PHP itself as well?

    The PHP version is 5.3.6.

    This site is hosted by GoDaddy and I have just taken over as webmaster. I suspect it is up to GoDaddy to update PHP. Wonder how hard it would be to move the site to a Linux server…

    Hi Darrell,

    Depending on the type of hosting plan, you may be able to select which version of PHP the site should use — many hosts allow that so you can choose to stay on a version that works with your site, but they would usually do minor updates. If you ask the host, they should be able to update it or switch it to a newer version for you.

    Upgrading PHP did the trick.

    Much obliged!

    Charlie

    Just FYI, we run Wordfence on multiple windows server and it has been working well for us.

    Upgraded to PHP 5.4.16, the latest available from GoDaddy. The Wordfence plug in will now activate, but is not working correctly. Looks like it is just not going to play nice with a Windows server. Unfortunately, we had to delete the Wordfence plugin. Perhaps we will migrate to a linux server at some point.
