Can't access WebUI after update to v2.029

I’m new to all of this, so sorry if this is the wrong way to do things.

My Pi2/HifiBerry DAC+ setup runs with only wifi (through the official rpi-wifi-dongle using “brcmfmac” as a driver).

This morning I updated to v2.029 through the webUI and restarted as per instructions. After this I can’t access the pi through the WebUI, but I can access the pi through SSH and I can ping urls. If I access 192.168.1.96:3000 I get the spinning wheel (see this screenshot), but the buttons at the bottom have weird holding-text.

Does anyone have an idea how to fix this? I tried restarting mpd and restarting the pi, but it didn’t help. Don’t hesitate to ask, if you need some kind of log-file or something.

The only non-stock modification I’ve made is to disable power-management on the wifi, since resume broke the connection. Thank you for making a lovely piece of software!

Could you please do

sudo journalctl -f (via ssh)

and paste here where you see error?

Sure.

volumio@volumio:~$ sudo journalctl -f

Well, I gave up and flashed the image directly to the memory card. Everything is working now, though I didn’t find a fix for the original problem.
