Openhab2 classic and basic ui not working

Hello everybody. new to openhab2 never used openhab1. installation went fine, I can bind and control devices from paper ui and habpanel. but, from basic ui I cannot get the state of devices. for example.
this is my .items file:
DateTime Date “Date [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]” { channel=“ntp:ntp:local:dateTime” }
Switch music “music” { channel=“squeezebox:squeezeboxplayer:2730DFB1-576D-4010-A5E1-41DF36C3C40E:b827ebcf1ae9:power” }
Dimmer dmusic “music volume [%.1f %%]” { channel=“squeezebox:squeezeboxplayer:2730DFB1-576D-4010-A5E1-41DF36C3C40E:b827ebcf1ae9:volume” }

…and this is my .sitemap
sitemap Home label=“Home” {
Frame label=“Date” {
Text item=Date
Frame label=“living” icon=“groundfloor” {
Default item=dmusic
Default item=music icon=“switch”

where is the mistake? thanks in advanced.
Also I want to ask if the item name in paper UI has to be the same with the name in .item

After changing the quotation marks it works fine.

DateTime Date "Date [%1$tA, %1$td.%1$tm.%1$tY %1$tH:%1$tM]" { channel="ntp:ntp:local:dateTime" }
Switch music "music" { channel="squeezebox:squeezeboxplayer:2730DFB1-576D-4010-A5E1-41DF36C3C40E:b827ebcf1ae9:power" }
Dimmer dmusic "music volume [%.1f %%]" { channel="squeezebox:squeezeboxplayer:2730DFB1-576D-4010-A5E1-41DF36C3C40E:b827ebcf1ae9:volume" }
sitemap Home label="Home" {
    Frame label="Date" {
        Text item=Date
    Frame label="living" icon="groundfloor" {
        Default item=dmusic
        Default item=music icon="switch"

no, it is not… I use notepad++ and just the paste changed them. The strange thing is that in classic ui if I use the _default sitemap, it works. and sometimes it works also for a moment.

this is how it supposed to show in paper ui?

…and by the way, the date is not updating if I don’t refresh the page in basic ui

ok, if I restart the server it starts to work…Icons no longer updating in BasicUI
here they explain it.
