Just upgraded to subsonic 5.1 and I'm using the webgui. Whenever I go to a new page (so far) I get a popup alert "escapeHHtml is not defined" then an Ok button.
Do let me know if there's a quick fix for this, but I have done nothing more than "dpkg -i" at this point
Also, awesome how easy it is to upgrade this software
I get this error message using Firefox on Ubuntu 14.04, but switching to chromium, it disappears. I can also see that artist info does not appear in Firefox, but it does in chromium. I've not yet found a solution to this as yet, but at least the webgui is useable in chromium!
