Title: Plugin broke entire WordPress? Last modified: February 6, 2021 --- # Plugin broke entire WordPress? * Resolved [sfelve](https://wordpress.org/support/users/sfelve/) * (@sfelve) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/) * After using the plugin uninteruppted for 3 years the Plugin broke my entire WordPress, this morning. * No matter what I do I get an error and if I activate it my entire WordPress breaks and I can’t even login to dashboard unless it’s through recovery mode. * WordPress version 5.6.1 Current theme: Enfold (version 4.7.6.3) Current plugin: CF7 Google Sheet Connector (version 4.6) PHP version 7.2.34 * Error Details ============= An error of type E_ERROR was caused in line 61 of the file * Error message: Uncaught Error: Call to undefined method GuzzleHttp\Utils::chooseHandler() in Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Author [WesternDeal](https://wordpress.org/support/users/westerndeal/) * (@westerndeal) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/#post-14011912) * [@sfelve](https://wordpress.org/support/users/sfelve/) Sorry for the trouble. 1. Are you using Facebook with a WordPress plugin? Recently it has been reported, that due to this plugin there is an issue. * So we have updated Google Library in our plugin as well. Can you make sure you updated this plugin version to 4.6? * If yes, facing the issue after update then can you roll back to 4.5 ? [https://downloads.wordpress.org/plugin/cf7-google-sheets-connector.4.5.zip](https://downloads.wordpress.org/plugin/cf7-google-sheets-connector.4.5.zip) * and if using 4.5 then update to 4.6 and check it out. Alternatively, for a while untill you test, enable the debug mode while enabling from wp-config.php using the following statements, when you are done with that remove this or set as false. * ``` // Enable WP_DEBUG mode define( 'WP_DEBUG', true ); // Enable Debug logging to the /wp-content/debug.log file define( 'WP_DEBUG_LOG', true ); // Disable display of errors and warnings define( 'WP_DEBUG_DISPLAY', false ); @ini_set( 'display_errors', 0 ); // Use dev versions of core JS and CSS files (only needed if you are modifying these core files) define( 'SCRIPT_DEBUG', true ); ``` * You will see debug log at /wp-content/debug.log Let me know what errors it might show you to help you further. * Many Thanks Abdullah * [chungonion](https://wordpress.org/support/users/chungonion/) * (@chungonion) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/#post-14013073) * I think there is an issue on 4.6 that breaks the contact form 7. I received 500 internal server error when attempting to submit a form with 4.6 installed, and while 4.5 works totally ok. * Thank you for your work! * [jesus2020](https://wordpress.org/support/users/jesus2020/) * (@jesus2020) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/#post-14020885) * Hola, tengo un problema desde que actualice su plug-in a la versión 4.6. * Voy a volver a la 4.5, pero por favor solucionen el problema. * `Fatal error: Uncaught Error: Undefined class constant ‘MAJOR_VERSION’ in /home/ galvani/public_html/cumplimientocaribe.org/wordpress/wp-content/plugins/cf7-google- sheets-connector/lib/vendor/guzzlehttp/guzzle/src/Utils.php:118 Stack trace: # 0 /home/galvani/public_html/cumplimientocaribe.org/wordpress/wp-content/plugins/ cf7-google-sheets-connector/lib/vendor/guzzlehttp/guzzle/src/functions.php(71): GuzzleHttp\Utils::defaultUserAgent() #1 /home/galvani/public_html/cumplimientocaribe. org/wordpress/wp-content/plugins/mailjet-for-wordpress/vendor/guzzlehttp/guzzle/ src/Client.php(194): GuzzleHttp\default_user_agent() #2 /home/galvani/public_html/ cumplimientocaribe.org/wordpress/wp-content/plugins/mailjet-for-wordpress/vendor/ guzzlehttp/guzzle/src/Client.php(75): GuzzleHttp\Client->configureDefaults(Array)# 3 /home/galvani/public_html/cumplimientocaribe.org/wordpress/wp-content/plugins/ mailjet-for-wordpress/vendor/mailjet/mailjet-apiv3-php/src/Mailjet/Request.php( 43): GuzzleHttp\Client->__construct(Array) #4 /home/galvani/public_ in /home/ galvani/public_html/cumplimientocaribe.org/wordpress/wp-content/plugins/cf7-google- sheets-connector/lib/vendor/guzzlehttp/guzzle/src/Utils.php on line 118 * Plugin Author [WesternDeal](https://wordpress.org/support/users/westerndeal/) * (@westerndeal) * [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/#post-14023623) * Hi [@jesus2020](https://wordpress.org/support/users/jesus2020/), * The version 4.6 contains the latest API library. * If you are having any issue then you can surely use 4.5 version. * Both 4.5 and 4.6 version are stable. * There are many plugins who have not updated there API library and clashing with each other. * As per the error there seems to be the conflict with the “mailjet-for-wordpress” plugin. So unless they don’t update you can use 4.5 version. * Thanks Abdullah Viewing 4 replies - 1 through 4 (of 4 total) The topic ‘Plugin broke entire WordPress?’ is closed to new replies. * ![](https://ps.w.org/cf7-google-sheets-connector/assets/icon-128x128.gif?rev= 3232650) * [GSheetConnector for CF7 – Connect Contact Form 7 to Google Sheets and Send Form Submissions in Real Time](https://wordpress.org/plugins/cf7-google-sheets-connector/) * [Frequently Asked Questions](https://wordpress.org/plugins/cf7-google-sheets-connector/#faq) * [Support Threads](https://wordpress.org/support/plugin/cf7-google-sheets-connector/) * [Active Topics](https://wordpress.org/support/plugin/cf7-google-sheets-connector/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/cf7-google-sheets-connector/unresolved/) * [Reviews](https://wordpress.org/support/plugin/cf7-google-sheets-connector/reviews/) * 4 replies * 4 participants * Last reply from: [WesternDeal](https://wordpress.org/support/users/westerndeal/) * Last activity: [5 years, 4 months ago](https://wordpress.org/support/topic/plugin-broke-entire-wordpress/#post-14023623) * Status: resolved
