Title: Outdated Guzzle Version Last modified: March 2, 2021 --- # Outdated Guzzle Version * Resolved [djcampanelli](https://wordpress.org/support/users/djcampanelli/) * (@djcampanelli) * [5 years, 3 months ago](https://wordpress.org/support/topic/outdated-guzzle-version/) * The plugin Constant Contact Forms has an older Guzzle version than the plugin Simple Sales Tax. They will not work together and they break the site. Can this be updated please? * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Foutdated-guzzle-version%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Constant Contact](https://wordpress.org/support/users/constantcontact/) * (@constantcontact) * [5 years, 3 months ago](https://wordpress.org/support/topic/outdated-guzzle-version/#post-14125723) * As is, I believe the plan is going to be staying with this version of Guzzle for the moment. This is because we’re exploring paths forward right now to update the plugin to use version 3 of our Constant Contact API, as opposed to version 2 which the plugin uses now. As part of that, we would be moving away from using Guzzle completely. * That said, it doesn’t help with your website, here and now. * Just to be certain, is this the “Simple Sales Tax” plugin you’re referring to?

I can’t make any promises on timeline for any amending or removal of Guzzle right now, and we’d rather you be successfully collecting contacts rather than fighting code errors. * [programmin](https://wordpress.org/support/users/programmin/) * (@programmin) * [5 years, 2 months ago](https://wordpress.org/support/topic/outdated-guzzle-version/#post-14300221) * I am also experiencing Guzzle error and it seems this would be happening whenever some other plugin or module in WordPress is also including Guzzle? * wp-content/plugins/constant-contact-forms/vendor/constantcontact/constantcontact/ src/Ctct/Services/ListService.php(31): Ctct\Services\BaseService->createBaseRequest * gets an exception: PHP Fatal error: Uncaught TypeError: Argument 3 passed to GuzzleHttp\Client::request() must be of the type array, string given, called in /(path to other Guzzle Client.php) * Plugin Author [Constant Contact](https://wordpress.org/support/users/constantcontact/) * (@constantcontact) * [5 years, 2 months ago](https://wordpress.org/support/topic/outdated-guzzle-version/#post-14300454) * Hi [@programmin](https://wordpress.org/support/users/programmin/) * Yes, it’s potentially going to happen whenever 2 plugins or even the theme have different versions of Guzzle available trying to run, and whose version attempts to be loaded. Definitely understandably frustrating. * Do you by chance know which other plugin has Guzzle included? * [programmin](https://wordpress.org/support/users/programmin/) * (@programmin) * [5 years, 2 months ago](https://wordpress.org/support/topic/outdated-guzzle-version/#post-14300463) * It is in our system and not publicly accessible. * Plugin Author [Constant Contact](https://wordpress.org/support/users/constantcontact/) * (@constantcontact) * [5 years, 1 month ago](https://wordpress.org/support/topic/outdated-guzzle-version/#post-14308381) * Understood, What I was trying to hopefully get was what the plugin was, in case it’s a publicly downloadable one from WordPress.org here to try and do some further deduction an debugging, to see if we could potentially resolve the conflicts in some way.
