I’ve managed to fix this as per @nathanaelphilip’s suggestion.
I can now confirm that the problem arose when the repeaters where separated by tabs with the same name as the repeater fields. When I changed the name of the tab separators the problem disappeared and the repeaters function as expected.
I’m having the same issue.
Illegal string offset ‘acfcloneindex’ …/advanced-custom-fields-pro/pro/fields/repeater.php:156
Invalid argument supplied for foreach() …/advanced-custom-fields-pro/pro/fields/repeater.php:255
Array to string conversion …/advanced-custom-fields-pro/pro/fields/repeater.php:156
This uses some repeater fields (that are obviously the problem) divided into tabbed sections.
I’m using 5.1.9.1
I’m having the same issue. I’m running WP 3.8.1, ACF 4.3.4 + Repeater Field 1.1.1. No console errors. The add media button appears (and works!) but no WYSIWYG.
I’ve deactivated all plugins and reactivated only ACF + repeater. No change.
WordPress is installed in a subdirectory, but that’s nothing new I guess.
I’ve noticed problems on some other of my sites too. Did they already switch to Tiny MCE 4.0 in 3.8.1? Might that be causing the problem. I know the API has changed…
