8.3 can not synx to itunes
 

when i was on ios 8 i could use my itunes and sync and add songs to my phone ok...now on ios 8.3 it will not let me sync my songs to my iphone 4s
i only realised this yesterday.....i even unstalled any think to do with apple and itunes so i could start again.
when i downloaded itunes again and set my phone up with usb port the phone was showing on itunes but didn't before so
i thought i might be on a winner here. so i added some songs and 142 songs to be sync but my phone was not syncing at all....
anyone having the same problem?
