Support » Plugin: WP Mail SMTP by WPForms » Latest Version 1.3.3 – PHP Fatal error – Conflict with Constant Contact Forms

  • Hi,

    After upgrading to the latest version (1.3.3) I have a fatal error due to a conflict with Constant Contact Forms for WP ( The Constant Contact Forms plugin was not recently updated and works with the previous version of WP Mail SMTP I had installed (1.2.5). Here is the error and stack trace:

    [13-Jul-2018 14:07:36 UTC] PHP Fatal error:  Uncaught TypeError: Argument 3 passed to GuzzleHttp\Client::request() must be of the type array, string given, called in /wp-content/plugins/wp-mail-smtp/vendor/guzzlehttp/guzzle/src/Client.php on line 89 and defined in /wp-content/plugins/wp-mail-smtp/vendor/guzzlehttp/guzzle/src/Client.php:128
    Stack trace:

    Hi @bburgay,

    Thanks for the report.
    We will test the plugin against Constant Contact.
    Can you prepare a step-by-step tutorial of how to replicate this error? How should I set up the plugin and what should I do to generate this error?

    Hi Slava,

    Thanks for the reply. Here are the steps to reproduce:

    1. Setup a new Constant Contact form.
    2. In the form settings check “No page refresh”.
    3. Under Contact Form > Settings make sure “Disable E-mail Notifications” is unchecked.
    4. Place the form on a page and try to submit.

    Let me know if you are unable to reproduce as these are just my settings and I haven’t tried a fresh setup to reproduce. I don’t think you should have to connect the plugin to a Constant Contact account as the error is coming from the Email notification sent to the admin email on submit.
