Sorry to resurrect this one. Seems I have come across this issue myself. So I have cleaned out all revisions and queried the db for the repeater field I am using:
Here are the results
79 30 page_blocks
1997 3876 page_blocks 2
2222 3882 page_blocks 3
3311 3927 page_blocks 6
5228 4002 page_blocks 1
Each is a page in the site. So the process is:
Change the field type in the ACF editor to Flexible Content
Then specifically how do I figure out what serialized array to enter into each page?
