I have the same problem. I have created a repeater field that is used on the_front_page, where the admin can insert google map coordinates. The admin has inserted over 200 fields of coordinates which results in a Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 32 bytes).
Memory is set to 256MB in the wp-config.php and on server, so there should be plenty of memory.
This issue only appears in the backend, editing the page.
I am using ACF Version 4.3.9 and ACF repeater field Version 1.1.1.
Is there a chance that ACF Version 5.1.5 will run better regarding this?
