Experiencing a similar issue with some ACF custom fields not saving. There were suggestions online to increase the max_vars to a larger size to allow the custom fields to save, but even after I increased these max vars to 50,000 as a test, and updated docker, the custom fields were still not saving. I also tried to rename the custom fields to make sure there are no duplicates or possible name conflicts. Are there any other methods I should try that may help solve this issue?
The only way I can think of now is to separate some custom fields into separate sections/pages but overtime this would lead to a bit of clutter since they would have to keep getting divided… Thank you in advance for any advice!
