Hi, ok there is still some default-handling missing in hocr-proofreader. It seems that your hOCR does not have a "scan_res" option. You can try to add title="scan_res 300 300" to a top-level-node (if you have 300 dpi resolution). Or you can play around in hocr-proofreader.js (line 304) for testing.
