Plugin doesn't work with Gravity Forms v1.7.7

While waiting for an official fix you can do the following:

Open up gravity-forms-multi-currency.php

Replace all references of:
$form[‘currency’]

with
$form[‘custom_currency’]

There are 13 references. Should work after that.

Hey Zane,

As of v1.7 I get 13 occurrences.

Here’s my fixed file.

Oooo – that’s a tricky one.

You could try to badger around with the init() function in GFMC.

Currently it’s set to detect if there is already an instance of itself and return the object if it is.

Try removing the test for self::$instance and see what happens.

Could lead to weird stuff though.

Let me know how you go.

Hey guys this helped me. Thanks!
