@sxi_k I updated ukadoc's sakura script page about 5 hours ago to hide jsstp related buttons when jsstp doesn't work, just like the event page
Sorry for the hassle.

You could try f12 in the page and check the js error log, that might work
Generally speaking the likely cause is that the browser is intercepting jsstp requests to the local port for security reasons, adding a whitelist or changing the relevant settings may fix this.
