The version is now 5.1.0… have you tried the latest version ?
Great to know I wasn’t alone
I have same problem when creating a brand new Repeater Field. First “Save” isn’t really saved it only save the Custom Field. I need to recreate the Repeater Field a second time to be saved.
Not a big deal since it’s saving on the second try but can be a pain for those who haven’t notice this bug.
Same here. Using the Pro version ACF 5.0.7 with WP 4.0 and WPML 3.1.7.2
I have to desactivate WPML and re-enable it after to be able to save custom field inside a page or article.
