Error in phpMyAdmin after updating to v4.8.0: The $cfg['TempDir'] (./tmp/) is not accessible

Question

phpMyAdmin worked fine with v4.7.9. Now after updating to v4.8.0 today (replacing the old phpmyadmin folder against the new one) I\'m getting this mess

Answer 1

For me phpmyadmin dir was found inside /opt/lampp/

1. open teminal inside /opt/lampp/phpmyadmin/
2. give root privileges to the terminal by typing sudo su command.
3. now in same terminal use (mkdir -p /tmp/) hit enter
4. now, chmod 777 /tmp
5. Inside phpmyadmin directory there is a file config.inc.php. Open it using same terminal .
6. add this line $cfg['TempDir'] = /tmp; and Save.
7. Now you are good to go , just reload the tab and the error will be gone.
