Plesk users often receive the error “Can’t create transaction directory file” while login to Plesk GUI.
At Bobcares, our Support Engineers often get the request to solve Plesk GUI problems as a part of our Server Management Services.
Today, let’s analyze the cause and see how our Support Team fix this login error for our customers.
What causes Plesk error “Can’t create transaction directory file”?
Recently we received a support request from one of our customers that they are unable to log in to Plesk GUI. We were receiving the error as below:
We also noticed that the Plesk keeps loading and the following error was found in
/var/log/plesk/panel.logCopy Code
This error mainly happens due to missing or incorrect permissions of the tmp directory. For RHEL-based OSes, this error will be
/usr/local/psa/tmp/.Copy Code/opt/psa/tmpCopy CodeHow to fix Plesk error “Can’t create transaction directory file”?
The first step that our Support Engineers take is to find out if the /tmp folder is missing or not. We try to list the folder after connecting through SSH with the commands below:
For RHEL-based OSes (CentOS, RHEL, CloudLinux):
# ls -d /usr/local/psa/tmp
ls: cannot access /usr/local/psa/tmp: No such file or directory
For Debian and Ubuntu OSes:
# ls -ld /opt/psa/tmp
ls: cannot access '/opt/psa/tmp': No such file or directoryCopy Code
The “No such file or directory” message indicates that the /tmp folder is missing. If the folder exists already, we also make sure that the folder is having the required permission with the command below:
For RHEL-based OSes (CentOS, RHEL, CloudLinux):
# stat -c "%a %U %G %n" /usr/local/psa/tmp
1777 root root /usr/local/psa/tmp
For Debian and Ubuntu OSes:
# stat -c "%a %U %G %n" /opt/psa/tmp
1777 root root /opt/psa/tmpCopy Code
If the permission is different from the one below, we need to correct it. For the case with missing folders , we make sure that the Plesk

For Debian and Ubuntu OSes:

If the issue is with the permission of the /tmp folder, we correct it with the command below:
For RHEL-based OSes (CentOS, RHEL, CloudLinux):
# DIR="/usr/local/psa/tmp"; chmod 1777 "$DIR" && chown root:root "$DIR"
For Debian and Ubuntu OSes:
