DirectAdmin - Error reading his/her user files

When you try login via DirectAdmin and get the following error:

Error reading his/her user files

At first you should check the correct permissions in folder - /usr/local/directadmin/data/users:

drwx--x--x 3 diradmin diradmin 4096 Jan 24 06:10 user1
drwx--x--x 3 diradmin diradmin 4096 Jan 24 06:10 user2
drwx--x--x 4 root root 4096 Jan 23 20:01 user3
drwx--x--x 3 diradmin diradmin 4096 Jan 24 12:25 user6
drwx--x--x 4 diradmin diradmin 4096 Jan 24 06:10 user4
drwx--x--x 4 diradmin diradmin 4096 Jan 24 06:10 user5

If some users' folders have uncorrect permissions - you must fix these by the command like this:

# chown diradmin:diradmin -R user3

Now try login via panel again.
