Background of the issue:
I am trying to translate ACF repeater fields that are nested inside another ACF repeater. The issue can be seen on this page: hidden link. There is a tabbed section that is causing a critical error see screen shot.

Symptoms:
I encountered a critical error when your plugin tries to translate the array as a string. The error message is: 'Warning: Array to string conversion in /Users/nathanfarleigh/Local Sites/casa-de-campo-development/app/public/wp-content/plugins/acfml/classes/class-wpml-acf-blocks.php on line 164'. Additionally, there is a fatal error: 'Uncaught TypeError: strlen(): Argument #1 ($string) must be of type string, array given in /Users/nathanfarleigh/Local Sites/casa-de-campo-development/app/public/wp-content/plugins/wpml-string-translation/classes/filters/strings-filter/class-wpml-register-string-filter.php:193'.

Questions:
Can you fix your plugin to handle nested acf repeater content?
