Parameters for custom post type not saved

Hi,

I have many custom post type like “patrimoine”, “garage”, etc…

I’m trying to modify the plugin parameters for the differents customs posts type but the changes are not saved.

This is the error message :
“The following settings were not saved:
apost_patrimoine_root
apost_garage_root
apost_local-commercial_root
apost_bien-immobilier_root
apost_contact_root
apost_faq_root”

I don’t understand. Do you have an idea of the issue ?

Thanks.
