Hi there. I’m a long time user of ACF and never had a problem. It seems however all of a sudden my plain vanilla ACF field on pages won’t save. I’m sing WP4.0 with ACF version 4.3.9, the text field input is appearing however on page update the field contents will not save. I’ve tried a few different things including removing and reinstalling the plugin but to no avail. Any ideas would be appreciated.
