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

I just changed my vendor_config.php file to define('TEMP_DIR', '/tmp/'); instead of define('TEMP_DIR', './tmp/');

This seems to work.
