# df -h


Filesystem                             Size         Used       Avail        Use%      Mounted on

/dev/sda1                                    75G            23G         49G            100%           /tmp

The error can be occurred because of /tmp partition is full on the server.



Remove the unwanted files and make the disk space available or allocate extra disk space to /tmp directory.


2. Incorrect permissions

Check permissions of server /tmp directory.

Check permissions of users /tmp directory.

Set the directory permission as 755 by using the following command:

# chmod 755 /home/username/tmp


3. Check “session.save_path” in php.ini file.

Open php.ini file.

# vi php.ini

Find the below line:

;session.save_path = “/tmp”

Remove the first semicolon from this line and set as:

session.save_path = “/tmp”

Restart apache service.

# service httpd restart
