Changing PHP Max Input Vars

Hi all,

I downloaded a theme which requires me to have a PHP Max Input Vars of 5000 but the set up has created a 4000 for me.

Looking online, I can only find instructions for changing it via phpMyadmin not local. Could someone please help with this? Is it possible to change this in a local environment?

I am a beginner FYI :slight_smile:
Thanks in advance!
