i faced this problem when i open phpmyadmin.
I was installed, php7.0, nginx, and phpmyadmin 4.7.2 (Download the file and unzip it, put in /usr/share/phpMyAdmin , granted permission 0755)
I have no problem when run the php files, i still can check my php file, just cant open the phpmyadmin. Any clues on it?
UPDATE 1
After i check the log file located in /var/log/php-fpm/www-error.log
, and then I try this with the command /sbin/restorecon -R /usr/share/nginx/html/phpMyAdmin
then it show up another error which i need to enable a mbstring.
