I've been using your plugin on my WordPress site for a couple of years now without any issues. However, as of yesterday, I've encountered a problem I can't seem to solve.
I'm using a custom field of type "select" to provide a list of options, which I then use in the admin panel to add fields to a custom post type. After modifying the list of choices in the custom field, all fields vanish in the custom post type edit page. Not just the fields I've changed, but all fields. All data is emptied except for the post's title.
Interestingly, the data still shows correctly on the main Custom Post Type page which displays the table with all posts and admin column info. This leads me to believe the data is still present in the database.
I have tried debugging and troubleshooting potential plugin conflicts, but I haven't been able to identify the cause of this issue.
Could you please provide some guidance on this matter? Are there known issues that could lead to this kind of behavior or steps I could take to further diagnose and solve this problem?
