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 problem but none of the answers above could solve. In my case my php security settings was so strict protecting php to access directories out of scope defined in open_basedir located at my /etc/php.d/99-security.ini(which I added perviously from a security toturial and the settings also could be located at /etc/php.ini file in your case):

;; Limit PHP Access To File System
; Limits the PHP process from accessing files outside
; of specifically designated directories such as /var/www/html/
open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/"

change to:

open_basedir="/home/:/etc/phpMyAdmin/:/var/lib/phpMyAdmin/:'/usr/share/phpmyadmin/tmp/"  ;<== changing to this solved the prblem

you just need to add your own directory in error mesage ('/usr/share/phpmyadmin/tmp/') and the end of open_basedir option. Don't forget placing separator : before adding it.
