The tab order of the ACF WYSIWYG field seems to have been reversed. I mean that the “Text” tab appears first (left to right) and is defaulted while the “Visual” tab appears afterward. This only seems to occur for the ACF WYSIWYG fields. All other WYSIWYG fields everywhere else whether in a (3rd party) metabox or not appear normal and as I’d expect.
Using ACF v5.1.5 / WP v4.1 on PHP v5.4.x / Apache (Local)
Hi,
This problem has been fixed in the current version of acf.
Update to the latest version of acf to solve the problem.
