Recently I came across following when deploying webapplication on Linux serevr…
SoftException in Application.cpp:303: UID of script “/home/xyz/public_html/en/pupgrade.php” is smaller than min_uid
The problem was file owner and group as root (I was uploading file through root account)
Solution: change file owner and group to webhoting user.. generally it is your user name..
The linux command for this task is
$ chown -R username:usergroup directory
