Support » Plugin: Mollie for Contact Form 7 » Cannot activate plugin

  • When I try to activate the plugin, I get the following error:

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

    Fatal error: Uncaught Error: Call to undefined function _PhpScoper5f8847d7a6e47\GuzzleHttp\choose_handler() in /html/wp-content/plugins/cf7-mollie/includes/libs/mollie-api-php/vendor/guzzlehttp/guzzle/src/HandlerStack.php:39 Stack trace: #0 /html/wp-content/plugins/cf7-mollie/includes/libs/mollie-api-php/src/MollieApiClient.php(257): _PhpScoper5f8847d7a6e47\GuzzleHttp\HandlerStack::create() #1 /html/wp-content/plugins/cf7-mollie/includes/php/initialize.php(16): Mollie\Api\MollieApiClient->__construct() #2 /html/wp-content/plugins/cf7-mollie/includes/php/webhook.php(2): require_once(‘/html/wp-conten…’) #3 /html/wp-content/plugins/cf7-mollie/includes/php/amount.php(2): require(‘/html/wp-conten…’) #4 /html/wp-content/plugins/cf7-mollie/cf7-mollie.php(12): require(‘/html/wp-conten…’) #5 /html/wp-admin/includes/plugin.php(2297): include(‘/html/wp-conten…’) #6 /html/wp-admin/plugins.php(191): plugin_sandbox_scrape(‘cf7-mollie/cf7-…’) #7 {main} thrown in /html/wp-content/plugins/cf7-mollie/includes/libs/mollie-api-php/vendor/guzzlehttp/guzzle/src/HandlerStack.php on line 39

    What is the problem and how can I solve it?
    Thanks

  • I’m not sure what exactly is going on with the error, but it seems there somehow is an issue loading a commonly used software library.

    If the issue persists after reinstalling the plugin, you might want to have a look at the Pronamic Pay plugin, which also supports Mollie and Contact Form 7 for one-off payments.

    How can I quickly solve this?
    Wordpress version: 5.6
    ContactForm version: 5.3.2
    CF Mollie plugin version: 4.8.0

    Thanks for your quick reply!!

    Similar problem here. It was a fresh install from contact form 7 and the mollie plugin.
    Worrying that this serious problem is still happening after 3 months?
    Has it been solved? What was the solution??

    I hope to get a response, as the last one raising the flag didn’t…

    I did some ttroubleshooting.
    The problem occurs only when you already have installed a plugin which uses an older version of GuzzleHttp.

    You should be able to activate the plugin when you deactivate all othe plugins except cf7

    Mollie issue

    Thanks @tsjippy, I managed to activated it now, and the other plugins thereafter as well.
    It looks like it’s working now.
