Incorrect Cron Job URL

Hello,

We have this plugin setup for manually triggering e-newsletters with post links to all users in an intranet site. We recently started having issues with not all of the recipients getting the emails.

We have authenticated the domain with the email server yet the problem persists.

I noticed while checking the settings that the “Cron Job URL” is incorrect. It’s pointing to a staging server URL we used in the past during development, however there’s no way to update this. Could this the the issue with not all of the emails being sent? How do I update it. Via the DB?

Additionally, in the “Sent Mail” screen. The last run date for the last email sent shows “NA”.

Any help would be greatly appreciated.
