MariaDB phpMyAdmin White PAGE?

For some reason phpmyadmin shows white page after fresh installation, i had this happening on my other servers too. Can't remember how it got fixed..

iptables:
-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 53 -j DROP
-A INPUT -p tcp -m tcp --dport 80 -j DROP
-A INPUT -p tcp -m tcp --dport 3306 -j DROP

 

I ran it through CLI, and i see mbstring is missing..?
