Tell us what you are trying to do? I am building a new site. I have created a post type. I then create a field group but it does not seem to successfully get assigned to the post type. I have set access control for the post type. I have also tried deleting and recreating the type and the field group multiple times with not change. The site is a managed WordPress site through Laughingsquid. I have also tried deactivating other third party plugins, but that did not make a difference.
I did see the note on your site about PHP 8.2 causing issues? I am not sure if that may be related.
Is there any documentation that you are following? I am following your tutorial videos.
Can you please try to follow that and check if that helkps. If it does not help then please send me admin access details and I'm happy to investigate further.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
