    When trying to generate an eBook with the “Validate content before download” option ticked, I get a bad gateway error:

    On chapter: such and such. <html> <head><title>502 Bad Gateway</title></head> <body> <center><h1>502 Bad Gateway</h1></center> <hr><center>nginx/1.18.0 (Ubuntu)</center> </body> </html>

    I changed themes to one of WordPress originals, tried multiple different posts, and the error persists.

    When I untick the validation request, the process leads to “critical error on this website” white screen error.

    I am running the latest WordPress version in MU format.

    Hello @mirrorspirits

    The plugin uses an external service (https://about.validator.nu/) for content validation, and they may experience some service errors on their side. As you experienced, unchecking the validation checkbox may be enough to skip this step.

    However, the white screen is not something I would expect. I understand you tested with different posts and the same results, so I have a few questions: Does it happen with all formats or just one of them? Do you have access to your debug.log? In this case, do you have an explicit error? Can you try with a test post (just plain text, no images, no link, etc.) to see what happens?

    Thanks.
