[Forminator Pro] File upload size in Forminator Pro seems to be limited. What settings in php.in w

I have a form created in Forminator and in the file upload->Edit->Settings view I get this message…

*We've detected your server will all uploads up to 1MB in size currently. You can set a lower limit than this using the input below, however if you want uploads of more than 1MB you'll need to adjust this in your server PHP.ini settings.*

In my php ini settings I have the file upload size as 128 MB.. what do I need to fix to increase this limit from 1 MB? And is this limit per field or per form?
