We're sorry to hear you're having trouble with your feeds. We looked up your domain in our feed error logs, and we found your most recently created Autoposter connector (for GrabPress versions up to 2.3.7, the connector is created upon plugin installation).
However, when I queried the feeds associated with your connector, there were no feeds. Additionally, I couldn't find any errors associated with your connector ID.
Question 1 - have you recently updated the WordPress users and permission levels in your WordPress admin? For GrabPress versions up to 2.3.7, you need to make sure the 'grabpress' user is in your WordPress Admin Users list, with Editor or Administrative rights. Also, the API key displayed on your Autoposter page (also in your WordPress MySQL DB) should match the password for the 'grabpress' user.
Note: The 'grabpress' WP Admin user (added upon plugin activation) will be deprecated in our upcoming release, and replaced with WordPress REST API OAuth. The goals are to better integrate with the native WordPress platform/API and make the user better aware of the GrabPress authentication process.
Question 2 - Have you checked your WordPress error logs? If there are any GrabPress specific errors found, please let us know.
Let us know if that helps you track the issue down. We're very interested to know what the issue is here.
