Problem:
If you're experiencing issues with ajax errors when adding choices to a custom field created with ACF, and you're using WP All Import and WP All Import - ACF Add-On, the problem might be due to compatibility issues among these plugins.
Solution:
We recommend updating both the WP All Import PRO plugin and the WP All Import - ACF Add-on to their latest versions. This update has resolved similar issues for other clients and might fix the ajax error you are encountering.

If updating does not resolve the issue, please contact our support team for further assistance. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
