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 had the same error message. I'm using Ubuntu16.04 with lampp. You should go to 'phpmyadmin' directory, in my case '/opt/lampp/phpmyadmin/', create a new 'tmp' folder. Open a terminal window and:

cd YOUR_PATH_TO_PHPMYADMIN
sudo mkdir tmp

Now you have to change the group of the 'tmp' folder to give access to php user. In order to find it, you can create a php file inside your localhost directory, in my case 'htdocs'

sudo touch user.php
sudo nano user.php

Inside nano editor, type:

Then press CTRL + O and CTRL + X to save and exit. Open the browser and type in your address bar

localhost/user.php

It shows your php user.

After that, go to the terminal and navigate to your recently created 'tmp' directory inside phpmyadmin directory and type:

sudo chgrp YOUR_PHP_USER tmp -R

And change the permission to the 'tmp' directory:

sudo chmod 775 tmp -R

I recommend never give 777 permission to any file.

I hope it helps!
