Wordpress Error on Upgrade to v1.13.0

[broksonic21]

Happens on multiple sites

Notice: Undefined variable: postmark in /app/wp-content/plugins/postmark-approved-wordpress-plugin/postmark.php on line 457 Fatal error: Uncaught Error: Call to a member function load_settings() on null in /app/wp-content/plugins/postmark-approved-wordpress-plugin/postmark.php:457

Admin then gets an email saying a terminal error existed.

I'm seeing this as well across multiple sites. Possibly related https://github.com/wildbit/postmark-wordpress/issues/39?

Site appears to be working fine, but please let me know if there is something that needs to be done to complete the upgrade manually.

Hi @EatonZ,

Thanks for the report! No further action is needed to complete the upgrade. WordPress recently introduced new error catching for plugins that revealed this upgrade error. The error is fixed in v1.13.2 of the Postmark for WordPress plugin, so future upgrades will not have this error moving forward.
