Title: Dependency problem Last modified: July 21, 2021 --- # Dependency problem * Resolved [flim0](https://wordpress.org/support/users/flim0/) * (@flim0) * [4 years, 10 months ago](https://wordpress.org/support/topic/dependency-problem/) * Authorizer works great, but WordPress crash after I activated a plugin called Collaboration by dPlugins. * The crash caused by the GuzzleHttp dependency conflict, Authorizer supporting php < 7.x and using the older GuzzleHttp that still support the php < 7.x * Is it possible to upgrade GuzzleHttp to higher version? * Thank you.

This won’t namespace the dependencies, but it may get you up to the same version of guzzlehttp used by the other conflicting plugin. * One other option to try is to request the other plugin be namespaced as well… they may be faster than us getting an update out! * FYI this is the fix we expect to use, `php-scoper`: [https://github.com/sureswiftcapital/Simple-Calendar/issues/341](https://github.com/sureswiftcapital/Simple-Calendar/issues/341) * Plugin Author [Paul Ryan](https://wordpress.org/support/users/figureone/) * (@figureone) * [4 years, 9 months ago](https://wordpress.org/support/topic/dependency-problem/#post-14812725) * Aloha, we reached out to the dPlugin folks and they provided us with a testing copy of the Collaboration plugin. However, we had no problems activating both Authorizer and Collaboration plugins at the same time. * Can you provide more details on the specific error message(s) related to the guzzlehttp/guzzle library, and what specific actions trigger the error? * Thread Starter [flim0](https://wordpress.org/support/users/flim0/) * (@flim0) * [4 years, 8 months ago](https://wordpress.org/support/topic/dependency-problem/#post-14830428) * This is the system error email when enabled Authorizer and Collaboration.

You may want to reach out to the Collaborator developers as well and ask them to scope their dependencies; they may have more luck getting a fix out sooner than us. * We’ll keep you updated on progress here! * Plugin Author [Paul Ryan](https://wordpress.org/support/users/figureone/) * (@figureone) * [4 years, 8 months ago](https://wordpress.org/support/topic/dependency-problem/#post-14906976) * Aloha, we weren’t able to get php-scoper to work for our specific dependencies so we have just updated our minimum PHP version to `7.2.5` which should force` guzzlehttp/guzzle` to the same version used by your other plugin, aether.
