Seems like some actions like posting generates an error message. Note that it actually posts the message despite the pop up error message. I am trying to diagnose. But for now, just refresh the page and your post should show up.
Thanks for the report. You had it recently? I did make a change mid-day that broke everything but I fixed it in 5 to 10 minutes. It should not be failing now.I just had a servor error. I think it was a 501. I tried four five times and couldn't access ASR. I checked if the site was down and it wasn't.
I unplugged my wi-fi internet cable and I plugged it back on, wirelessly.
That reset did the trick.
