Can't save my settings for phpmyadmin

[kinnth]

I'm having an issue where none of my variable changes are being saved in phpmyadmin. I've made sure that a DB is setup for phpmyadmin and i've logged in as root to edit my various settings to ensure it's not a permission issue, but everytime I change the settings they are later overwritten / reset to the default settings.

How can I ensure my settings are saved forever, I feel it's a db access issue for myphp user.
