Support » Plugin: Simple Calendar - Google Calendar Plugin » Version 3.1.11 causes error

  • Resolved vultan


    Simple Calendar was working great for me, then I did the upgrade to 3.1.11; now I get this error:

    Fatal error: Call to undefined function GuzzleHttp\Handler\curl_reset() in /home/oremetor/public_html/wp2/wp-content/plugins/google-calendar-events/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php on line 78

    The whole website is now dead, unless I disable the plugin. Any suggestions?

    Currently, NO version works with PHP 7.2!

    Hey @wetapplemedia

    As mentioned in the other thread, we’re working on a fix so that the plugin is compatible with 7.2.

    Thank you again for reporting the bug & for posting your workaround in the meantime.



    Zach, thanks for the fix. I’ve got two websites I’m using this on; on the one I had already upgraded to PHP 5.5.13, it installed without a problem. On the site running PHP 5.4.13, it refused to activate until I upgraded PHP, which I did. So on my end, everything is now working as it should. Thanks so much for the quick response.

    Hey @vultan

    I’m very happy to hear that. Please don’t hesitate to reach out if you run into other problems.



    Après la nouvelle mise à jour, Voici ce que me répond OVH, premier hébergeur en France:

    Simple Calendar could not be activated.
    Required PHP version: 5.5 – Version found: 5.4.45
    Please update to meet Simple Calendar requirements.

    Version 3.1.10 is only 816 files while the latest version is over 7500 files. What is the cause of this massive increase and can this be restored?

    Hi @oxymoron

    The fix for prevents the plugin to activate for those of us with older versions of PHP. It does prevent the crash. Are there plans to address the older versions of PHP so that the plugin will install and work as before? Unfortunately I am on a hosting package and can’t change the PHP version.

    The increase in files is because of the update to the Google API PHP Client Library v2 (

    @rkovacs123 & @webxwebywebz

    In the meantime, you can download and run version 3.1.10 from here:

    The new requirements for PHP 5.5 stem from upgrading the Google API PHP Client Library to v2. We are reviewing our decision to make that update and deciding whether or not it makes sense to roll back the library version used in the plugin to the previous one (which is compatible with older PHP versions).
