Fatal error: PostmanLicenseManager (Undefined index: Class)

[Andrew Huguenard]

This is in regard to a report I on the WordPress.org forum. Tim advised that I Should post it here.
Original post: https://wordpress.org/support/topic/fatal-error-postmanlicensemanager-undefined-index-class/

I can confirm that this issue still hasn’t been resolved. Steps taken to produce the error:

Post SMTP installed and activated
Post SMTP Office365 Extension installed and activated
Went to Post SMTP in the Left Nav, clicked Extensions, added the key that was generated at checkout, and got the error below.

Hi Andrew,

Thanks for posting. What version of Post SMTP and the extension are you running?

Kind Regards,
Tim

[Andrew Huguenard]

Yes that would help 🙂

Office 365 for Post SMTP Extension – Version 1.2
Post SMTP – Version 2.0.21
WordPress 5.5.3

Thanks!

[Tim]

Hi Andrew,

Are you able to update your WP core?

Kind Regards,
Tim

[Andrew Huguenard]

Yes. I deleted the extension from the server, updated WP core to 5.6.1, re-uploaded the extension and upon activation this time (not when adding the key) the site crashed. Error log below:

FYI I’m in a SANDBOX environment so there isn’t an immediate urgency, but it would be great to implement this to the LIVE site soon. Thank you!

Hi Andrew,

Okay, could you paste a copy of your Post SMTP diagnostics log? If you want to keep your site info private, please mark the reply as “private” using the relevant checkbox below. Your reply will then only be visible to you, me, and the plugin creator – Yehuda.

Thanks.

Kind Regards,
Tim

When I click on “Diagnostic Test” I get a fatal error. Unless there’s a separate diagnostics log saved somewhere else?
