White Screen – 500 Internal Server Error

Hi there

I’m working on a multisite setup and have installed and activated the Publish to Apple News plugin network wide. I have setup the plugin on one of our sites and it publishes to Apple News fine. I have setup the plugin with exactly the same settings on another site (same API details) but when I try to publish an article, I just get a white page in Safari and a 500 Internal Server Error on Chrome.

Apple have approved our channel, however I am currently waiting for them to approve our first article.

Does anyone know what may be causing the issue or where to begin with troubleshooting? Could the multisite setup be causing issues with API calls from multiple domains?

I’ve included the 7 error messages in the logs that seem to be related to a failed publish. (DOMAIN = I’ve taken out our domain identifiers)

Many thanks for your help,
James
