error with puligins quser and qsmartboard

hi,

the plugins quser is shhown an error when i log in, is the first image attached. when i press "ok" it does nothing, if i refresh the page the user seems to ble logged in but can not make any call even with clients on the wating list.

the qsmartboard plugin works fine for about 5 minutes, after that it doesn't show a number anymore, after refreshing the page it shows the numbers again, even makes the calls that were called before refreshing.

i am using version 17.2

thanks
