 * Hey mebishwak,
 * The issue actually stems from another plugin using an older version of Guzzle,
   not an issue with other HubSpot plugins.
 * I am going to try to push up a new version this week that will check for that
   function (Client::request) when activating, in order to throw a conflict warning
   and keep this plugin deactivated, because you are not the first to encounter 
   this.
 * As for solutions to the problem… there aren’t many on my end. There is a conflicting
   plugin that’s also using Guzzle. A cursory glimpse of your plugin list has shown
   no known outliers that I’ve dealt with previously, but a file search can turn
   up the culprit.
 * There isn’t many solutions on my end because my only real option is to prevent
   you from using the plugin at all with a proper warning (instead of crashing)…
   The other “option” is to downgrade my version of Guzzle, but that introduces 
   security concerns (it’s better to be on newer versions).
 * Let me know if you have any luck finding the culprit?
