I have a custom module I have created that does a few things regarding the batch API.
It has a few operations to delete nodes and a few to import nodes. All good. It's just that when I'm taken to the batch page I see nothing. I see the progress bar appear briefly, then go away. After that, it's just a reloading blank page.
I'm happy it works, but a progress indicator would be nice. Any ideas why that would happen?
