There is nothing special really. Just a simple gallery website with CPT UI and ACF.
I created a new CPT and added a page with a repeater to test how it works. Apparently within the selector, I can see that the repeater is selectable but do data is shown on the frontend.
Now if I do the same thing on a normal page instead of a post or CPT element, it is displayed correctly.
With custom fields it is sometimes difficult to find out what the problem is, so I asked you to show how you created your fields and used the repeater to rule out a mistake on your part (can happen ).
We could identify the problem in the meantime, so it will be fixed in the next version.
Is it possible for you to send us one email to help@bricksbuilder.io and share with us temporary login details so we could investigate what the issue is? Please mention this forum post and let us know what is the ACF Repeater field and on which page are you using it.
Yes, this was fixed in Bricks 1.4 RC2. If this is still not working for you let us know by sending us one email to help@bricksbuilder.io mentioning this forum thread and if possible, with login credentials to your WordPress installation so we could check it.
