Support » Plugin: Gmail SMTP » Guzzle Fatal Error

  • Resolved nelsonleemiller


    I am getting this fatal error. I believ ethis is due to an old version of the guzzle PHP library that your plugin uses. Please advise on a fix or an ETA on when this will be updated.


    Fatal error: Uncaught Error: Undefined class constant 'MAJOR_VERSION' in /home/ Stack trace: #0 /home/ GuzzleHttp\Utils::defaultUserAgent() #1 /home/ GuzzleHttp\default_user_agent() #2 /home/ GuzzleHttp\Client->configureDefaults(Array) #3 /home/ GuzzleHttp\Client->__construct(Array) #4 /home/ in /home/ on line 118

    @nelsonleemiller, The plugin doesn’t directly use the Guzzle library. It includes the Google api client library which requires this library.

    In this case it seems to be conflicting with the Guzzle library included by the pixel caffeine plugin. I don’t think you can do anything other than deactivating one plugin or use another SMTP plugin that doesn’t use it.
