Conditional rules error

Suddenly after updating acf to the v4.3.1 the following error has started popping up:

Warning: array_values() expects parameter 1 to be array, string given in /home/ringvhfx/public_html/wp-content/plugins/advanced-custom-fields/core/fields/_functions.php on line 431

The error appears during printing of a flexible content field.

I checked the source, and found that it must be related to conditional rules. I don’t use any conditional rules in my flexible content field (or any other place on my site, really).

What might be causing this?

Hi @stiaje

I’m not sure how your conditional logic could be a string, can you please export your field group to PHP and copy / paste the flexible content field in question so I can see what the conditional logic value is?

If the export doesn’t work due to this error, perhaps look in the db wp_postmeta table where the post_id = field group ID, the meta_key = field_key and then copy out the meta_value

Thanks

The php export is:

I should also note, all content is printed. It just comes after the warning message.

Hi @stiaje

Thanks for the field group code.
None of the above fields contain any conditional_logic data, so i can’t understand why you are receiving an error complaining that a the value of ‘conditional_logic’ is a string.

I also pasted your code into my functions.php file and the fields load correctly without any errors.

I think the error must come from another field group.
