Need assistance on where to place USER.ini in a cpanel account

My WP theme advised me to update resources on my Godaddy hosting. Godaddy suggested I use a USER.ini file. In the past on other accounts, I used php.ini. Before looking to see if the changes registered, I killed the PHP processes so it would reset. However, the changes I made in the user.ini file do not appear to change the settings I made, as shown when I do info.php. Currently, I have a godaddy hosting account and I put the user.ini file in the public_html folder where my WP is installed. Do I need to add it to other folders.
