[Solved] Lost "System" page after updating Web-UI via git

Yep, this is your best bet… Sorry…

Good new everyone!
I have “fixed” the problem.
The issue was not only in unavailable Spotify(sh*ttify) service, but in broken(?) i2s select elements in setting.php
After I disabled them and commented the $spop = openSpopSocket(DAEMONIP, 6602); line in inc/connection.php the page loads fine.

Which were the broken elements?

I’m not shure if they are really broken. But after disabling them the page is normally loads on my Cubietruck. Maybe them are only for Raspberry?

Yes, and they should be hidden… Thank you for reporting, this helps me!

Thanks Acid_Reptile!

The commenting out of the i2s options in settings.php works for me as well.
