Apply one of the following workarounds:
Clear cookies in your web-browser.
Remove phpMyAdmin session files:
Connect to the Plesk server via SSH.
Clean the phpMyAdmin session directory:
# rm -rf /usr/local/psa/var/phpMyAdmin/session/*
If the phpMyAdmin session directory has been customized, run the command below to find the actual directory:
# egrep "'SessionSavePath'" /usr/local/psa/admin/htdocs/domains/databases/phpMyAdmin/libraries/config.default.php
If neither of the workarounds above help, reinstall phpMyAdmin (users' data will not be affected):
Remove the phpMyAdmin package:
on CentOS/RHEL-based distributions
# rpm -e --nodeps psa-phpmyadmin
on Debian/Ubuntu-based distributions
# dpkg -r --force-depends "psa-phpmyadmin"
Run the Plesk Installer update command to install phpMyAdmin:
# plesk installer update --repatch
If the issue persists, run Plesk repair utility as follows:
# plesk repair installation
