I am a little panicked…
I have just updated ACF to newest Version (4.3.2) and since then I get lots of Errors all saying Warning: array_values() [function.array-values]: The argument should be an array in xxxx/site/wp-content/plugins/advanced-custom-fields/core/fields/_functions.php on line 439
I have tried deactivating all plugins and have updated WordPress to 3.7.1 with no luck.
I have one field group with four simple fields. The errors are shown in backend and frontend.
