Issue is partially resolved. It seems only field data used in sidebar.php (in this instance) is not properly updating for any fields, both new or old. Perhaps this is a change in the general functionality of the plugin? Guess I need to do some more testing for possible conflicts and dig through the docs a bit more.
I’m getting a similar problem.
After the most recent ACF update today neither previously existing textarea (WYSIWYG) fields will update to the front end nor new textarea fields show up on on the front end for previously existing pages/post types. The fields do however update in the admin side. The changes simply do not propagate to the front end. However on any new pages/post types created the fields update as expected.
Please let me know if my explanation isn’t clear. Thanks!!
P.S. Your plugin seriously rocks! Best plugin around for WordPress by far. Really turned it into a legit CMS.
