For some reason one of the sites I built using ACF is having some issues with checkboxes. This website is using the latest ACF plugins as well as the latest WordPress. We recently realized that when we uncheck a checkbox from a custom post type we generated and update. The checkbox wont uncheck.
Also we have a taxonomy field in the Options section. As soon as we try to check or uncheck a box, all of the Options pages custom fields disapear. The only thing left is the “Update” button, however when you update nothing saves.
@elliot thanks for getting back to me. Unfortunately this is not the case for either of these problems. I do not have another field with the same value, and I do ot have “Save / Load terms to post” selected. I am happy to share my login credentials if you want to take a peak. Do you have a way of doing that?
