The error indicates that phpMyAdmin is encountering problems during session initialization. Specifically, it’s failing to write session data due to a lack of available space on the device where the session files are stored.
Possible Causes
Disk Space Exhaustion: The most common cause is that the disk where your session data is stored has run out of space.
Incorrect session.save_path: The session.save_path configuration in your PHP settings might be incorrect.
Check Disk Space
First and foremost, check the available disk space on the device where your session files are stored. You can use the df
command to view disk space information:
df -h
If the disk is full or nearly full, you’ll need to free up some space by removing unnecessary files or expanding the storage capacity.
Verify session.save_path
Verify that the session.save_path
in your PHP configuration is correctly set. Open your php.ini
file and ensure that the session.save_path
points to a directory with sufficient space. In your case, it’s set to /opt/lampp/temp/
.
session.save_path = "/opt/lampp/temp/"
Clear Session Files
If your disk space is limited, you may have accumulated a large number of session files. Clearing old session files can help free up space. Run the following command to delete old session files:
sudo find /opt/lampp/temp/ -type f -name 'sess_*' -delete
Adjust PHP Session Configuration
Consider adjusting other PHP session-related configurations to optimize session management. This might include tweaking the session timeout settings and garbage collection.
Restart Services
After making changes, restart your web server (e.g., Apache) and PHP to apply the modifications:
sudo service apache2 restart
sudo service php7.4-fpm restart # Replace with your PHP version
