Field ID not being updated, data can't be pulled, can't use MB

Hello Long, thank you for your quick response.

I figured out in the meantime that I needed to re-save the custom post type posts individually to erase the content of the old meta_keys. So by opening again the custom posts individually, the fields had become blank (after renaming their IDs), and by re-entering the data field by field, it would remove the old meta_keys no longer in use, and replace them with the new ones, and allow me to pull them. Another way round was to just copy/paste the meta_key ID without trying to find it in the list, as Oxygen allows that.

So now my fields are correctly populated, but I do have an issue with Single Images that do not want to come, I have no idea why. A broken image thumbnail pictogram shows (Chrome), no way to have it show up. Should I open another thread for this question ? Thank you in advance for your help.

Hi,

This the PHP code generated through the WP back-office builder. All fields can be succesfully pulled, apart from the single image "dlc_media_photos_couverture".

FYI "dlc_media_photos_choix" corresponds to an Advanced Image field, where we can upload a gallery of images.
