Increasing max input vars

I have been trying to increase the max input vars on my cpanel (wordpress)
But no luck. Any suggestions? I have changed it in htaccess, php.ini, user.ini, wp-config, and also on multiphp ini editor.

I am trying to make some changes on my builder of the website (to the front end) and when I click update it just loads and never updates. What could be wrong?
