Fatal error: Uncaught InvalidArgumentException: in cms

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client encountered a fatal error in the 'translate custom fields' section within 'WPML > Settings'. The error prevented rendering of sections below it and was resolved by disabling the 'Advanced Custom Fields Multilingual' plugin.
Solution:
We are aware of this issue and our developers are currently working on a fix. In the meantime, we recommend following the workaround provided in our errata page: https://wpml.org/errata/fatal-error-uncaught-invalidargumentexception-item-should-be-a-collection-or-an-array-or-an-object-when-visiting-wpml-settings/.

We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.

frankB-3	Fatal error: Uncaught InvalidArgumentException: item should be a Collection or an array or an object in /home/redacted/public_html/wp-content/plugins/sitepress-multilingual-cms/vendor/wpml/fp/core/Obj.php:112 This error displays at the bottom of the 'translate custom fields' section in 'wpml > settings'. It is unable to render the sections below it due to this error. When i disable "advanced custom fields multilingual" the error is removed. Please note: The provided debug info may include 'memory limit: 40'. This appears incorrect- both the server and phpinfo display 128M as the memory limit.
