Phptmp error is flooding the log

Hi guys,

I have since NC11 (maybe before) an error that is flooding the log.

{“reqId”:“xxx”,“remoteAddr”:"",“app”:“no app in context”,“message”:“Temporary directory /home/www/USER/phptmp/ is not present or writable”,“level”:2,“time”:“2016-12-17T08:45:01+00:00”,“method”:"–",“url”:"–",“user”:"–",“version”:“11.0.0.10”}

There is a phptmp folder present in my root folder and that one has fully rights (777). Maybe the location is wrong I have honestly no clue. Would be nice if somebody could point me in the right direction.Thanks in advance.
