I have inherited maintenance for a WordPress site and I have limited access - I can see the dashboard and the File Manager (through a Plugin) but I cannot see the database.

There is a piece of custom code that the last maintainer inserted somewhere that creates repeated fields in a Gravity form. I need to modify that code, but I can't see where it is. I have checked functions.php of the theme and also the Snippets plugin. In the web Inspector I can see that the fields that get created with the gfield_repeater prefix in their html class names which makes me think that this class is being called but I cannot see the actual code that calls it, or the arguments that are being passed.

Any ideas?
