Btw, I’m temporarily circumventing this issue with some jQuery code, triggering the ajax event manually so that the correct display is loaded.

It was only happening on index. I though the same thing (in regards to broken block), but it was happening from line 1. The file was definitely a php file running in WP, and I checked the permissions (644).

I eventually determined that the file was corrupted. Made a new index.php and pasted in the same code, worked fine.

I’ve never seen a corrupted file do that, but good to know.
