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

1) create the tmp folder

mkdir /usr/share/phpmyadmin/tmp

2) findout your php user

3) Change ownership of the tmp folder to the php user found in step 2

sudo chown -R step2phpuser:step2phpuser /usr/share/phpmyadmin/tmp

4) Signout of phpmyadmin and sign back in
