Thanks Elliot!
I can confirm this solves the issue.
It did not work immediately but it did after a hard refresh (shift+F5 or shift+CMD+R).
Reason it seemed to work with line changed to beta1 also had to do with caching and stopped working after a hard refresh, so forget what I stated in the earlier post 😉
So I tested a little more. I enabled beta 2 again. The boxes (as we know now) do not appear in the editor. If I change the following in acf.php the boxes magically re-appear.
In the description I changed:
From: Version: 5.8.0-beta2
To: Version: 5.8.0-beta1
In the code
From
var $version = '5.8.0-beta2';
To
var $version = '5.8.0-beta1';
However don’t know why this is happening.
Also experienced the same issue. So I rolled back to beta 1 and all is working fine again. Then there was this update notice of beta 2. So I updated again to see what happens and the block indeed disappeared again. Instead I got to see the following message:
Your site does not support the “acf/testimonial” block. You can leave this block or delete it completely.
WP 4.9.8
GB 4.1.1
ACF 5.8.0. beta2
Thanks MikeX for the link.
I hope this option will find its way to implementation soon. I think this will be a solution for so many.
